Question

Bob paid $1210 for five tables and seven chairs for his company. Each table cost three times as much as each chair. If Ann brought 8 such tables and 4 such chairs, how much money will she have to pay?

Answer 1

$1540

Explanation:

$1210=5T+7C

T=3C

8T+4C=?

1210=5(3C)+7C

C=$55

T=$165

8(165)+4(55)=1540
