7% interest rate. He borrowed 4500 for two years. The total amount he had to pay additional in interest was 630. 4500x7% is $315. But since it was 2 years you would do 315x2 which equals 630 which was the amount he ended up paying additional for the two years.

Solve the equation.<br> \qquad r - 14 = 23r−14=23

Nesterboy [21]

Answer: $r=37$

Step-by-step explanation:

For this exercise it is important to remember that:

1. The Addition property of equality states that:

If $a=b$ , then $a+c=b+c$

2. The Subtraction property of equality states the following:

If $a=b$ , then $a-c=b-c$

3. The Division property of equality states that:

If $a=b$ , then $\frac{a}{c}=\frac{b}{c}$

4. The Multiplication property of equality states the following:

If $a=b$ , then $a*c=b*c$

Then, having the following equation given in the exercise:

$r-14=23$

You need to solve for the variable "r" in order to find its value.

In order to solve for "r", you must apply the Addition property of equality adding 14 to both sides of the equation.

Therefore, you get the following solution:

$r-14+(14)=23+(14)\\\\r=37$

A stereo costs $320. in a sale it is reduced by 25% what is the sale price

Rudiy27

First, set up a proportion to find the reduction in price. 25/100=x/320. Cross multiply to get 8000=100x. Divide by 100 on both sides to get x=80. That's the reduction in price. Subtract from the total to find the new price 320-80=$240
