X is basically a variable. Now the thing is, that variables do not have a definite value, and that they can have an infinite range of values. While solving an equation in algebra, you don't know what your answer is going to be therefore, the answer could be infinite! :)
8.25%...to turn a percent to a decimal, start at the decimal and move it to spaces to the left.
8.25% = 0.0825
another way, is to divide ur number by 100
8.25 / 100 = 0.0825
1) Let, the original price = x
We know, sale price is 100 - 15 = 85% of original price.
So, x * 85% = 59
x * 0.85 = 59
x = 59/0.85
x = 69.41
In short, Your Answer would be Option B
2) Let, the original price = x
We know, sale price is 100 - 30 = 70% of original price.
x * 70% = 79
x * 0.70 = 79
x = 79/0.70
x = 112.85
In short, Your Answer would be $112.85
Hope this helps!
