Question

Three new roommates each pay toward the rent and groceries. Allison agrees to pay 35% of the costs, and Betsy agrees to pay 0.4 of the costs. Caroline will pay the remaining balance. Their first payment was $1,160, and their first grocery bill was $130. Caroline claims the she owes $322.50 toward theses two costs. Is her claim correct?

Answer 1

She is correct

Explanation:

The total amount the three roommates must pay is $1,160+$130= $1,290

Allison must pay:

$1,290*0.35= $451.5

Betsy must pay:

$1,290*0.4= $516

Both Allison and Betsy payments sum: $967.5

Caroline must pay: $1,290-$967.5= $322.5

She is correct because she agreed to pay the remaining balance, which in this case is $322.5
