Question

If 5 hours at a computer terminal costs $25, what is the cost of 6 hours?

A. $30
B. $45
C. $150
D. $12

Answer 1

It would be B

Explanation:

First, we need to find out the unit rate

5/25=1/5

Therefore, that means in one hour the cost would be $5

Since you are going from one hour to 6 hours you need to multiply both numbers by 6

Since 5x6=30, it would be 30$ :)

Answer 2

30 dollars

Explanation:

25/5 = 5 dollars per hour

so 6 hours would be 5 * 6 = 30 dollars
