Question

Erin and Dan went shopping at their local store. Erin bought shirts that cost $12 each and spent $18 on accessories. Dan bought the same number of shirts as Erin for $16 each and spent $10 on accessories. If Erin and Dan were billed the same amount by the store, how many shirts did each of them buy?

Answer 1

Each bought 2 shirts.

Step-by-step explanation:

Number of Shirts Bought by Erin = X

Number of Shirts Bought by Dan = Y

Price of Erin Shirt = $12

Price of Dan Shirt = $18

Spending by Erin = $12X + $18

Spending by Dan = $16Y + $10

As given in Question

Spending by Erin = Spending by Dan

$12X + $18 = $16Y + $10

$12X + $18 = $16X + $10 (Dan bought same Number of Shirt as Erin)

16X - 12X = $18 - $10

4X = 8

X = 8/4

X = 2

Each bought 2 shirts.
