Finley’s friends all chipped in to buy her a wedding gift. At first, ten friends agreed to contribute the same amount. Then two “friends” dropped out. The remaining eight had to add another dollar each to cover the cost of the gift. How much did the gift cost?
$40.
Let x be the amount the ten friends initially agreed to pay. We can then make the following equation:
10x = 8x + 8
Solving for x gives us $4, thus the gift cost 10 × $4, or $40.
