Question

Grayson's retirement party will cost $60 if he invites 10 guests. If there are 86 guests, how much will Grayson's retirement party cost? Solve using unit rates.

Answer 1

Grayson's party will cost $516.

Explanation:

Start with putting a unit rate for money per person

60/10

Divide by 10

6/1 (6$ per person)

Then multiply by 86 (# of guests attending)

86 x 6 = 516
