Question

Selena and Demi run a gift delivery business. Selena charges a delivery fee that is $18, and she also charges $6 per gift delivered. Demi charges $16, and she also charges $8 per gift delivered. How many gifts have to be delivered before they charge the same amount?

Answer 1

1 gift

Explanation:

Cost per gift + delivered cost

Selena $6x + $18

Demi $8x + $16

$8x + $16 = $6x + $18

$2x - $16 = $18

$2x = $18 - $16

$2x = $2

x = 1
