Question

Liz and Elena baked some cookies.

The total number of cookies they baked is 35.

Liz baked 11 more cookies than Elena.

How many cookies does Liz bake?

Worked Solution

Solution 1 (Trial and error)

If Liz baked 19 ⇒ Elena baked 8 (27 total)

If Liz baked 21 ⇒ Elena baked 10 (31 total)

If Liz baked 23 ⇒ Elena baked 12 (35 total) \checkmark

\therefore Liz baked 23 cookies.


Solution 2 (Algebra)

Let  n\ \large n = number of cookies Elena baked

n\large n + 11 = number of cookies Liz baked

n\large n + n\large n + 11 = 35
2n2\large n = 24
n\large n = 12


\therefore Liz bakes = 12 + 11 = 23 cookies

Question

Kane and Abel spread some topsoil over their lawn.

The total number of cubic metres of topsoil they spread is 17.

Kane spread 5 more cubic metres than Abel.

How many cubic metres does Kane spread?

Worked Solution

Solution 1 (Trial and error)

If Kane spread 8 ⇒ Abel spread 3 (11 total)

If Kane spread 10 ⇒ Abel spread 5 (15 total)

If Kane spread 11 ⇒ Abel spread 6 (17 total) \checkmark

\therefore Kane spread 11 metres.


Solution 2 (Algebra)

Let  n\ \large n = number of metres Abel spread

n\large n + 5 = number of metres Kane spread

n\large n + n\large n + 5 = 17
2n2\large n = 12
n\large n = 6

Question

Gunther and Gertrude are filling jars with marmalade.

The total number of jars of marmalade they have filled is 68.

Gunther fills 16 more jars than Gertrude.

How many jars does Gunther fill?

Worked Solution

Solution 1 (Trial and error)

If Gunther fills 36 ⇒ Gertrude fills 20 (56 total)

If Gunther fills 40 ⇒ Gertrude fills 24 (64 total)

If Gunther fills 42 ⇒ Gertrude fills 26 (68 total) \checkmark

\therefore Gunther fills 42 jars.


Solution 2 (Algebra)

Let  n\ \large n = number of jars Gertrude fills

n\large n + 16 = number of jars Gunther fills

n\large n + n\large n + 16 = 68

Question

Johnny and Evie are picking strawberries.

The total number of buckets of strawberries they have picked is 104.

Johnny picks 42 more buckets than Evie.

How many buckets does Johnny pick?

Worked Solution

Solution 1 (Trial and error)

If Johnny picks 70 ⇒ Evie picks 28 (98 total)

If Johnny picks 72 ⇒ Evie picks 30 (102 total)

If Johnny picks 73 ⇒ Evie picks 31 (104 total) \checkmark

\therefore Johnny picks 73 buckets.


Solution 2 (Algebra)

Let  n\ \large n = number of buckets Evie picks

n\large n + 42 = number of buckets Johnny picks

n\large n + n\large n + 42 = 104
2n2\large n = 62

Question

Charlie and Linus are counting sheep.

The total number of sheep they have counted is 741.

Charlie counts 181 more sheep than Linus.

How many sheep does Charlie count?

Worked Solution

Solution 1 (Trial and error)

If Charlie counts 481 ⇒ Linus counts 300 (781 total)

If Charlie counts 471 ⇒ Linus counts 290 (761 total)

If Charlie counts 461 ⇒ Linus counts 280 (741 total) \checkmark

\therefore Charlie counts 461 sheep.


Solution 2 (Algebra)

Let  n\ \large n = number of sheep Linus counts

n\large n + 181 = number of sheep Charlie counts

n\large n + n\large n + 181 = 741

Question

Dakota and Duke are mustering cattle.

The total number of cattle they have mustered is 2500.

Dakota musters 420 more cattle than Duke.

How many cattle does Dakota muster?

Worked Solution

Solution 1 (Trial and error)

If Dakota musters 1400 ⇒ Duke musters 980 (2380 total)

If Dakota musters 1430 ⇒ Duke musters 1010 (2440 total)

If Dakota musters 1460 ⇒ Duke musters 1040 (2500 total)

\therefore Dakota musters 1460 cattle.


Solution 2 (Algebra)

Let  n\ \large n = number of cattle Duke musters

n\large n + 420 = number of cattle Dakota musters

n\large n + n\large n + 420 = 2500
2n2\large n = 2080
n\large n = 1040


\therefore Dakota musters = 1040 + 420 = 1460 cattle
