Spiral Review 99

15. Roberto paid $35.75 for dinner at a restaurant, plus an additional $7.15

tip. What percent of the bill did he pay as a tip? Round to the nearest

percent, if necessary.

He paid 17% of the bill as a tip.

Step-by-step explanation:

Paid $35.75 for dinner at a restaurant, plus an additional $7.15 tip.

So in all, he paid 35.75 + 7.15 = $42.9

Tip as a percent:

Tip(7.15) multiplied by 100 and divided by the total(42.9). So

7.15*100/42.9 = 16.7%

Rounded to the nearest percent

He paid 17% of the bill as a tip.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
