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.
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.
