**5)**Benjamin went to the clothes store and purchased a blue shirt for $18.45, a red shirt for $22.18, a green shirt for $28.97. What was the average price he paid for a shirt?

Answer:

To figure the average we must total the cost of the shirts and the divide by the total number of shirts (which is three).

$18.45 + $22.18 + $28.97 = $69.60 total cost

$69.60 ÷ 3 = $23.20.

The average price that Benjamin paid for a shirt was $23.20.

**6)**A gallon of gas costs $2.90. How much would it cost to fill up a car with a 15 gallon tank?

Answer:

$2.90 x 15 = $43.50

**7)**At the store you see two sizes of peanut butter jars. One size is 23.96 ounces and sells for $5.99. The other size is 12.5 ounces and sells for $3.00. Which is the better deal per ounce?

Answer:

Figure out the per ounce price of the first jar:

$5.99 ÷ 23.96 ounces = .25 or 25 cents per ounce

Now, figure out the per ounce price of the other jar:

$3.00 ÷ 12.5 ounces = .24 or 24 cents per ounce

The second jar is a better deal because it is less money per ounce.

**8)**The bill at a restaurant is $38.00. The service was good, so you decide to tip 20%. What is the new total with tip included?

Answer:

First figure out the tip:

$38.00 x .2 = $7.60

Another way to figure this out is to move the decimal over one place and double the amount. This would be $3.80 x 2 which is $7.60.

Next, add the tip to the bill:

$38.00 + $7.60 = $45.60

**9)**Alice purchased 18 bolts of cloth. Each bolt has 12 yards of cloth. A yard of cloth costs $2.35. How much money did all the cloth cost Alice?

Answer:

First figure out how much each bolt of cloth cost:

12 yards times $2.35 for each yard = 12 x $2.35 = $28.20 per bolt

Now multiply the bolt cost by the number of bolts purchased:

18 bolts x $28.20 = $507.60

Alice spent $507.60 total on cloth.

**10)**Three friends made $435 together each month for a year cleaning houses. At the end of the year they divided the money evenly. How much money did each friend earn for the year?

Answer:

First figure out how much money they made together in a year:

$435 x 12 = $5220

Divide the total up between the three friends:

$5220 ÷ 3 = $1740

Each friend made $1740.
