Question

Select the correct answer. The number of oranges purchased varies directly as the price of the oranges. If 11 oranges cost $2.35, what is the cost of 18 oranges? A. $3.85 B. $85.71 C. $84.24 D. $2.35

Answer 1

Explanation:

3.85

Answer 2

A. 3.85

Explanation:

• If 11 oranges cost $2.35, we could calculate the cost of each of these oranges, simply dividing the total cost ($2.35) between the amount of oranges bougth (11). This will give us the cost of a single orange, that is, the unitary cost=
  `(2.35)/(11)= 0.21`.
• Then, if we want to know the cost of 18 oranges, we just have to multiply the cost of a single orange (0.21) by 18: 0.21x18 = 2.85
