Answer 5

Carrots sell for $2.10 per pound, and crackers sell for $2.90 per pound. Glen bought some carrots and some crackers. The total weight was 2.3 pounds and cost $6.03.

Let p represent the number of pounds of carrots.

Which equation represents the situation described?


A.
–0.8p + 6.03 = 6.67

B.
2.1p + 2.9 = 6.03

C.
–0.8p + 6.67 = 6.03

D.
2.1p + 6.03 = 2.9

Answer 6

B, because carrots are $2.10 per pound, and p represents pounds, so 2.1p would give you the price of the carrots.
Crackers are 2.90 so you add that to the previous and set it equal to the total price, 6.03.

2.1p + 2.9 = 6.03
