Final answer:
Noelle paid 57.6% of the original price for an item, calculated by dividing the amount she paid by the original price and multiplying by 100, then rounding to the nearest tenth of a percent.
Step-by-step explanation:
To calculate what percent of the original price Noelle paid for an item, we need to divide the amount she paid by the original price and then multiply by 100 to convert the fraction to a percentage. The steps listed below can help you locate the answer:
- Divide the amount Noelle paid ($190) by the original price ($330).
- To convert the value to a percentage, multiply it by 100.
Now let's do the math:
$190 ÷ $330 = 0.575757...
Multiplying this by 100 gives us:
0.575757... × 100 = 57.5757...
When rounded to the nearest tenth of a percent, we get 57.6% as the percentage of the original price that Noelle paid for the item. Therefore, the correct choice is (a) 57.6%.
