A DVD was priced at $2.87 last week. This week the same DVD is priced at $10.59. What is the percent increase in price?

solniwko [45]

Answer:

Percentage increase = 269%

Step-by-step explanation:

Price of a DVD last week = $2.87

Price of the same DVD this week = $10.59

Increase in the price of DVD between last week and this week = 10.59 - 2.87

= $7.72

Therefore, percentage increase in the price of DVD = $\frac{\text{Increase in the price}}{\text{Price of DVD last week}}\times 100$

= $\frac{7.72}{2.87}\times 100$

= 268.99

= 269%
