Question

Susie bought 3 pies all for the same price and a snickers bar for $1 Emma bought one of same pies and spent $9 on flowers, they both spent the same amount, how much did each pie cost

Answer 1

Let x be the price of one pie.

3x + 1 = x + 9
3x + 1 - 1 = x + 9 - 1
3x - x = x - x + 8
2/2x = 8/2
x = 4
The pies cost $4
