Question

Miko’s restaurant bill was $16. She used the expression 1.18(16) to find the total cost including an 18% tip.

Which expression is equivalent to the amount Miko paid?

16 + 1.18

1 + 0.18(16)

(16 + 0.18)16

16 + 0.18(16)

Answer 1

The answer is (1+0.18)16.

Answer 2

we have that

the expression to find the total cost is equal to

$1.18(16)$

we know that

$1.18=(1+0.18)$

substitute in the expression above

$1.18(16)=(1+0.18)16$

Applying property distributive

$(1+0.18)16=(1)*16+(0.18)*16=16+0.18*(16)$

therefore

the answer is the option

$16+0.18(16)$
