You treat your friend to lunch. The food bill was $30.24. A 7% sales tax will be added and you want to leave a 20% tip.
KiRa [710]

Answer:

a. $2.12

b. $6.45

c. $38.81

Step-by-step explanation:

a.

I'll convert 30.24 and 7% into fractions.

756/25 * 7/100

<em>Cross cancel 756 and 100 (GCF is 4)</em>

189/25 * 7/25

<em>Convert above into a single fraction</em>

(189 * 7)/(25 * 25)

<em>Multiply 189 by 7, then 25 by 25.</em>

1323/625

<em>Divide, then round to the nearest cent</em>

$2.1168 ≈ $2.12 in sales tax

b.

Like before, I'll convert $32.26 ($30.24 + $2.12) and 20% into fractions.

1613/50 * 1/5

<em>Multiply 50 by 5.</em>

1613/250

<em>Divide, then round to the nearest cent.</em>

$6.452 ≈ $6.45 in tip money

c.

This is probably the simplest part of the 3. Just add $30.24 + $2.12 + $6.45.

$30.24 + $2.12 + $6.45

$32.36 + $6.45

You pay a total of $38.81 for lunch.
