Answer:
$48
Step-by-step explanation:
Find 1% of each pair of shoe first.
1 pair of shoe which cost $45:
100% = 45
1% = 45 ÷ 100 = 0.45
Other pair of shoe which cost $75:
100% = 75
1% = 75 ÷ 100 = 0.75
Now find 60% of each pair, the sale percentage.
1 pair of shoe which cost $45:
60% = 0.45 x 60 = $27
Other pair of shoe which cost $75:
60% = 0.75 x 60 = $45
Now, do full price - 60% of it.
$45 - $27 = $18
$75 - $45 = $30
Now add them up.
$18 + $30 = $48
(Final answer)
