Answer:
Every year, the deductions total up to $384 a year, because 12 x 32 = 384. :)
purchases * percentage discount = savings
purchases * .32 = 64
divide each side by .32
purchases = 64/.32
purchases = 200
He bought 200 worth of items before his discount
Answer: $200
Answer:
There would be 24 dimes and 76 quarters.
Step-by-step explanation:
In order to find this, start by defining the number of dimes by x and the number of quarters as y. Now we can create a system of equations. Make the first about the total number of coins.
x + y = 100
Make the second about the amount of money.
.10x + .25y = 21.40
Now we can solve using elimination by multiplying the second equation by -4 and adding through.
x + y = 100
-.40x - y = -85.60
-----------------------
.60x = 14.4
x = 24
Now we can use the amount of dimes we have to find the number of quarters.
x + y = 100
24 + y = 100
y = 76
It would be 50 cents each
If you are adding the fractions themselves it would be 9/17. If the /'s are for division it's 0.53
