Answer 1

Answer:

C. 10%

Step-by-step explanation:

Given:

Original price of shirt = $42.39

Current sales price of shirt = $38.15

Required:

% decrease in the price of shirt

SOLUTION:

Percentage decrease in price of shirt = change in price over original price, multiplied by 100%

Change in price = original price - current price = $42.39 - $38.15 = $4.24

% decrease = $\frac{4.24}{42.39}*100$

$= \frac{4.24*100}{42.39}$

$= \frac{424}{42.39}$

% decrease $= 10.00$
