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?

Respuesta :

Answer:

8%

Step-by-step explanation:

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

[tex]\$1.89 - \$1.75\\\\= 1.89 - 1.75\\\\= 0.14[/tex]

Step 2: Divide the increase by the original cost

[tex]0.14 \div 1.75\\\\\frac{0.14}{1.75} \\\\= 0.08[/tex]

Step 3: Convert the answer to percent

[tex]\frac{0.08}{1} \times \frac{x}{100}[/tex]

Cross multiply

[tex]0.08 \times 100\\\\= 8 \\\\= 8\%[/tex]

Therefore, 8% is the percent increase.
