Question

In January, a store sold a pack of collectible cards for $1.75. In February, they sold the same pack of collectible cards for $1.89. What is the percent of the increase?

Answer 1

Answer:

8%

Step-by-step explanation:

Step 1: Find the difference (increase) between the two costs

$\ 1.89 - \ 1.75\\\\= 1.89 - 1.75\\\\= 0.14$

Step 2: Divide the increase by the original cost

$0.14 \div 1.75\\\\\frac{0.14}{1.75} \\\\= 0.08$

Step 3: Convert the answer to percent

$\frac{0.08}{1} \times \frac{x}{100}$

Cross multiply

$0.08 \times 100\\\\= 8 \\\\= 8\%$

Therefore, 8% is the percent increase.
