Brandon has a jar of quarters and dimes with a total value of $7.05. The number of quarters is 3 less than twice the number of d
miv72 [106K]

Answer:

  • quarters: 23
  • dimes: 13

Step-by-step explanation:

Let d represent the number of dimes. Then the number of quarters is 2d-3 and the total value of the coins is ...

  0.10d + 0.25(2d-3) = 7.05

  0.60d -0.75 = 7.05 . . . . . . . simplify

  d = (7.05 +0.75)/0.60 = 13 . . . . add 0.75, divide by 0.60

  2d-3 = 2·13 -3 = 23

Brandon has 23 quarters and 13 dimes.

1.The price of a coat was priced at $300. It went on sale after Christmas. It had a 22% discount. What was the sale price?
LekaFEV [45]

Answer:

1. $234

2. B) 6

Step-by-step explanation:

1. Since the coat is on sale for 22% off you want to do 300 times 0.22 to get 66. With this number you are going to take 300-66 to get $234.

2. The formula for the volume of a rectangular pyramid is V= lwh/3

Since I know that the total volume is 120 I know that the l times w time h has to equal 360 since its divided by 3. With the 12 and 5 I get 60. Since I know that 360/60 equals 6 I know the answer is B.
