Question

Excuse me can you help it’s proportional relationship

Armstrong high school decided to purchase 30 lab coats one lab coat regularly cost $18.50 if a 15% discount is given on the total purchase how much will the lab coats cost..
Also can you help me with more sums

Answer 1

Sorry, I’m busy but I’ll help you with this one.

$18.50 x 30 = $555

100% - 15% = 85%

$555 / 100 = $5.55

$5.55 x 85 = $471.75

Lab Coats will cost $471.75
