Question

11. Liam, Lidea, Lisa and Larry bought a

gift for their soccer coach. The total
cost of the gift, including tax, was
$55.80. Liam paid $14, Lidea paid
of the cost, Lisa paid 25% of the
cost, and Larry paid the remaining cost.
Who paid the greatest part of the cost?
Prove mathematically!
​

Answer 1

Liam $14

Lidea 1/3 cost = $18.60

Lisa 25% = $13.95

Larry = $9.25

Step-by-step explanation:

Liam’s amount was given= $14

Lidea: 1/3 of $55.80 =$18.60

Lisa: 55.80 x .25 =$13.95

Lary: add up Liam’s, Lidea’s and Lisa’s payments ($46.55) and subtract that from $55.80 = $9.25

Lidea paid the greatest amount of the cost, as $18.60 is the highest amount paid between all of the friends.

Good luck!
