You purchased a shirt on sale for $17.55. The discount on the shirt was $5.85. What was the original price of the shirt?

Svetlanka [38]

To find the original price, add the discount back onto the sales price.
17.55+5.85= 23.4
So your answer would be $23.40. Hope this helps!

Find how many quarts of 6% butterfat milk and 1% butterfat milk should be mixed to yield 75 quarts of 3% butterfat milk.

Strike441 [17]

Answer:

30 gallons of 6% milk, and 45 gallons of 1% milk.

x=quarts of 6% butterfat

First, write an equation.

0.06x+0.01(75-x)=0.03*75

Multiply both sides by 100.

0.06x*100+0.01*100(75-x)=100*0.03*75

Simplify

6x+75-x=3*75

6x+75-x=225

Solve

5x=225-75=150

5x=150

x=30

75-30=45

So, we need 30 gallons of 6% milk, and 45 gallons of 1% milk.
