Answer 1

To find out how much money Riley needs to earn, we can use a proportional relationship.

Let's set up the proportion:

x/49.99 = 7.25/100

To solve for x, we can cross multiply:

100x = 49.99 * 7.25

Multiplying these two values, we get:

100x = 362.4375

Now, we can isolate x by dividing both sides of the equation by 100:

x = 362.4375 / 100

x ≈ 3.62

Therefore, Riley needs to earn approximately $3.62 to purchase the new jacket. Rounding to the nearest dollar, he needs to earn $4.
