Answer:

$8.80
40%

Step-by-step explanation:

The amount of the discount is the difference between the original price and the discounted price. That was ...

$22.00 -13.20 = $8.80

The percentage of the discount is the ratio of the amount of the discount to the original price. That was ...

8.80/22.00 × 100% = 40%

The price was discounted $8.80. That was a 40% discount.

What is the value of x

mezya [45]

Answer:

x=9.5

Step-by-step explanation:

In order to find the answer, we know that 6x + 4x - 5 = 90

Next we want to combine like terms: 10x - 5 = 90.

Now we have to add 5 to 90 in order to get x on its own. 10x = 95

Now solve for x by dividing 95 by 10: x=9.5

A collection of dimes and quarters is worth $10.45. There are 70 coins in all. Find how many of each there are

Advocard [28]

There are 47 dimes and 23 quarters.

Step-by-step explanation:

Total amount = $10.45 = 10.45*100 = 1045 cents

Total coins = 70

1 dime = 10 cents

1 quarter = 25 cents

Let,

Dimes = x

Quarters = y

According to given statement;

x+y=70 Eqn 1

10x+25y=1045 Eqn 2

Multiplying Eqn 1 by 10;

$10(x+y=70)\\10x+10y=700\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(10x+25y)-(10x+10y)=1045-700\\10x+25y-10x-10y=345\\15y=345$

Dividing both sides by 15;

$\frac{15y}{15}=\frac{345}{15}\\y=23$

Putting y=23 in Eqn 1

$x+23=70\\x=70-23\\x=47$

There are 47 dimes and 23 quarters.
