Question

Ally bought 1 pound of chocolate from the chocolate shop last week for $4. The next week the cost for the same pound of chocolate increased to $6. What was the percent increase in the cost of the pound of chocolate?

Answer 1

Answer:
`50\%`

Step-by-step explanation:

To solve this exercise you can use the following formula:

`\%increase=(New\ price-Old\ price)/(Old\ price)*100`

According to the information provided in the exercise, you can identify that:

`New\ price=\$6\\\\Old\ price=\$4`

Therefore, knowing these values, the final step is to substitute them into the formula and then evaluate, in order to calculate the percent increase in the cost of the pound of chocolate.

This was:

`\%increase=(\$6-\$4)/(\$4)*100\\\\\%increase=50\%`
