You are at a restaurant and your bill comes to $31.18. The sales tax is 6% and you give the waitress a 20 percent tip on the tot

Vanyuwa [196]

Answer:

$ 0.34 or 34 cents

Step-by-step explanation:

Bill amount = $31.18

sales tax = 6% of $31.18

= 0.06 ($31.18)

= $1.8708

Bill with tax = $31.18+$1.8708

= $33.0508

value of tip = 20% of 33.0508

= 6.61016

Total payment = 33.0508+ 6.61016

= $39.66096

or $39.66

We get change of $40 - $39.66

= $ 0.34

We shall get back in cents that will be 34 cents

three quarts of latex enamel paint will cover about 270 square feet of wall surface. how many quarts will you need to cover 350

hichkok12 [17]

Answer:

Kitchen - 3.89 quarts or 3 $\frac{8}{9}$ quarts of latex enamel

Bathroom - 1.12 quarts or 1 $\frac{1}{9}$ quarts of latex enamel

Step-by-step explanation:

270 feet² for every 3 quartz.

We need how much ft² 1 quart can cover.

So,

270 ÷ 3 = 90 ft²

Every 1 quart covers about 90 ft² of wall.

For kitchen we need to cover 350 ft².

So,

350 ÷ 90 = 3.89 quarts or 3 $\frac{8}{9}$ quarts of latex enamel

For bathroom we need to cover 100 ft².

So,

100 ÷ 90 = 1.12 quarts or 1 $\frac{1}{9}$ quarts of latex enamel
