Use proportional relationships to solve the following problem. Riley needs to earn enough money to purchase

Answer 1

a new computer. She currently has $200 saved and can earn $15 per hour by babysitting. Let's say she wants to save $800.

To find out how many hours she needs to work, we can set up a proportion:

$15 / 1 hour = $800 / x hours

Cross-multiplying, we get:

15x = 800

Dividing both sides by 15, we find:

x = 800 / 15

Simplifying the division, we get:

x = 53.33

Since Riley cannot work a fraction of an hour, we can round up to the nearest whole number. Therefore, she needs to work approximately 54 hours to save $800.
