The mark up on an item is $3.75. If the mark up is 35%, what was the original price? Round
oksian1 [2.3K]

Answer:

$10.71

Step-by-step explanation:

\frac{3.75}{y} =\frac{35}{100}

y × 35 = 3.75 × 100

35y = 375

35y ÷ 35 = 375 ÷ 35

y=10\frac{5}{7}

y = 10.7142857143

10.7142857143 round to 10.71
