Question

Justin went to a lolly shop to buy some sweets and spent $12.

He bought a chocolate bar that cost $5 and 7 pieces of liquorice that cost 40 cents each.

The rest of his money was spent on musk sticks that costs $0.30 each.

How many musk sticks did he buy?

Worked Solution
Money left = 12−5−(7×0.40)12 - 5 - (7 × 0.40)
= 7−2.807 - 2.80
= $4.20

∴\therefore Musk sticks = 4.2 ÷ 0.3
= 14

Question

Joanna went to the supermarket and spent $52.

She bought $15 worth of meat, 10 energy drinks costing $1.90 each and some bottles of water that cost $1.20 each.

How many bottles of water did she buy?

Worked Solution
Money left for water = 52−15−(10×1.9)52 - 15 - (10 × 1.9)
= $18

∴\therefore Bottles of water = 18 ÷ 1.2
= 15

Question

Nico spent $54 at the post office.

He bought a large box of envelopes for $17.

With the remaining money he bought 10 stamps at $1.30 each and some more stamps at 80 cents each.

How many 80-cent stamps did Nico buy?

Worked Solution

Calculate money left for stamps:

$54 − $17 = $37

$37 − (10 × 1.30) = $24

∴\therefore Number of stamps
= 24 ÷ 0.8
= 30
