For Each problem, set u a proportion. Include the units for each ratio. Then solve for the missing value and label your answer with appropriate units. Round answers to the nearest tenth.
Amy earned $25 after babysitting for 3 hours. If she always charges the same rate, how much will she make after working for 7 hours?
Let x represent the amount Amy will make after working for 7 hours.
We can set up a proportion using the relationship between the amount earned and the number of hours worked:
25 dollars / 3 hours = x dollars / 7 hours
To solve for x, we can cross-multiply:
3 * x = 25 * 7
3x = 175
Dividing both sides by 3:
x = 175 / 3 = 58.3
Therefore, Amy will make $58.3 after working for 7 hours.
