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? (1+0.2)35 35 + 0.2 1.02(35) 1+0.2(35)

Answer 1

Answer:

This equation would be equivalent to

1.20

(

35

)

. You would simply add

1

and

0.2

together to get the value of

1.20

. You would get this answer because whenever you are working with decimals, you can drop any zeros that are on the end of the number and the value would still be the same if you add or take away zeros past the decimal point and any numbers besides

0

. For example:

89.7654000000000000000000

.... is equal to

89.7654

.
