Question

10. RP3-M

Answer 1

Answer:

Jeannette's ticket was less than the original pice by 30%

Step-by-step explanation:

original price = $75

percentage discount = 20% of original price = 20% of $75

discounted price = $\frac{20}{100} \times\ 75\ =\ 15$

discounted price = $15

website service fee = 10% of original price

website service fee = $\frac{10}{100}\times 75 = \ 7.5$

New discounted price = discount price + website service fee

= 15 + 7.5 = $22.5

Next, let us calculate what percentage of the original price that will give the new discount price.

Let the percentage of the original price = x%

x% of 75 = $22.5

$\frac{x}{100} \times\ 75\ = 22.5\\\\\frac{75x}{100} = 22.5\\\\75x = 2250\\\\x = \frac{2250}{75} \\\\x = 30$

Therefore, Jeannette's ticket was less than the original pice by 30%
