The cost of a regular-price ticket to a San Francisco Giants baseball game was $60. During the World Series, the price increased

lutik1710 [3]

First off, we need to determine what 2/5 is.
2/5 is 40% also known as .40

Now we multiply $60 by .40 and you get 24.

Now you add the two numbers.
60 + 24 = 84

The correct answer should be D, $84.

Hope this Helps!

Answer me step by step detailed

KengaRu [80]

Answer:

$11.25

Step-by-step explanation:

When finding a discount that has a percentage, we have to multiply the amount of the specific item being discounted and the percentage of the discount. In this case, we have a forty-five dollar headset at a twenty-five percent discount rate. To find the price, multiply the amount of the headset by the percentage of the discount.

$45 * 25%

$11.25

Meaning that the price of the discount will be eleven dollars and twenty five cents.
