Question

Mariana buys bottles of orange juice at the corner store. assume each bottle of juice is the same price. the proportional relationship between the number of juice bottles bought, j, and the total cost in dollars and cents, c, can be represented by the equation c=0.8jc=0.8j. what is the cost in dollars and cents of each bottle of juice?

Answer 1

By evaluating the function in j = 1, we conclude that each bottle costs 80 cents.

What is the cost in dollars and cents of each bottle of juice?

We know that the total cost in dollars can be represented by the linear equation:

C(j) = 0.8*j

Where C is the cost, and j is the number of juice bottles bought.

Then to get the cost of each bottle, we can evaluate the function in 1, which means buying only one.

C(1) = 0.8*1 = 0.8

So each bottle costs $0.80 (or 80 cents).
