Calvin paid $1.79 per pound of beans both times that he went shopping for supplies for a chili cook-off. he bought 4.05 pounds of beans the first time and 2.78 pounds the second time. which expression shows the total cost in dollars of the beans he bought? clear

Step-by-step explanation:

The cost for one pound of beans is $1.79

Calvin bought 4.05 pounds of beans the first time and 2.78 pounds the second time. The total cost for the first time is the amount of beans that he bought for the first time × the cost per pound of beans.

First time cost = 4.05×1.79 = $7.2495

The total cost for the second time is the amount of beans that he bought for the second time × the cost per pound of beans.

Second time cost = 2.78×1.79 = $4.9762

Let y represent total cost in dollars of the beans he bought. Then

y = 7.2495 + 4.9762

y = $12.2257
