Question

Santana is buying a guitar string.

Some of the strings are on sale.

Select the string that will be cheapest.

Worked Solution

Cost of each option:

$17

$35 less 50% = $17.50

$20 less 20% = 20−420 - 4 = $16

$24 less 25% = 24−624 - 6 = $18

∴\therefore "$20 Sale: take 20% off" is the cheapest string.
