Question

Luke has $120 to buy two watches that cost $58 each and one chain for $13. Select the answer that uses the best estimation to decide whether Luke has enough money.

Answer 1

We conclude that Luke does not have enough money to buy two watches and one chain, because $129 > $120.

Explanation:

We know that Luke has $120 to buy two watches that cost $58 each and one chain for $13. We caclulate whether Luke has enough money.

Therefore, we have

2 · $58 + $13 = $116 + $13 = $129

$129 > $120.

We conclude that Luke does not have enough money to buy two watches and one chain, because $129 > $120.
