Use proportional relationships to solve the following problem. Riley needs to earn enough money to purchase a new jacket. The one he likes best is $49.99. His sales tax is 7.25%. How much money does he need to earn round to the nearest dollar.

Answer 1

To find out how much money Riley needs to earn, we need to add the amount of sales tax to the price of the jacket.

Sales tax is calculated as a percentage of the price.

So, the amount of sales tax is 7.25% of $49.99.

To find this amount, we can multiply $49.99 by 0.0725 (which is the decimal form of 7.25%).

Amount of sales tax = $49.99 x 0.0725 = $3.624275

Round to the nearest cent, we have $3.62 as the amount of sales tax.

Now, to find out how much money Riley needs to earn, we add the price of the jacket ($49.99) and the sales tax ($3.62).

Total amount of money needed to be earned = $49.99 + $3.62 = $53.61

Therefore, Riley needs to earn $53.61 rounded to the nearest dollar.
