Question

kayla's mom left a 20% tip for a restaurant bill that was $35. she used the expression 1.20(35) to find the total cost. which equivalent expression could she also use to find the total cost? responses 35 0.2 35 0.2 (1 0.2)35 left parenthesis 1 plus 0.2 right parenthesis 35 1.02(35) 1.02 left parenthesis 35 right parenthesis 1 0.2(35)

Answer 1

Hi! It's pretty easy to find the answer to this so let me help you.

Were gonna find the total cost first using the equation shown in the problem.

1.20(35) = 42

Secondly, were going to go through the answers to see if it's equivalent to the cost.

35 + 0.2 = 35.2 (Not equivalent)

1 + 0.2(35) = 8 (Not equivalent)

1.02(35) = 35.7 (Not equivalent)

(1 + 0.2)35 = 42 (Equivalent)

We have come to our answer! So, the equivalent expression that could be used to find the total cost is:

(1 + 0.2)35

I really hoped this helped you and to further prove this I took a quiz in math and got this exact question and this was the answer. Have a lovely day/night <3
