Answer:
$46
Step-by-step explanation:
A percent is a portion of 100. If we receive 25% off then we pay 75% of the price. 100%-25%=75%. $34.50 is 75% of the original price. We find the new price through a proportion. A proportion is an equation where two ratios or fractions are equal. The ratios or fractions compare like quantities. For example, we will compare percent over percent to an equal ratio of $ to $.

I can now cross-multiply by multiplying numerator and denominator from each ratio.
I now solve for y by dividing by 75.
The original price was $46.
Answer:
10 rocks
Step-by-step explanation:
The cost on startup is $10 and each painted rock cost around $0.75 to make. A store pays startup cost and buy painted rocks for $0.75 each there no profit because the cost price and selling price is the same.
Domain is the set of x-values and range is the set of images f(x).
x F(x) = x + 7
-9 -9 + 7 = -2
-8 -8 + 7 = -1
-7 -7 + 7 = 0
-6 -6 + 7 = 1
-5 -5 + 7 = 2
-4 -4 + 7 = 3
-3 -3 + 7 = 4
So the range is {-2,4} <------ answer
