Things we know: every pound of cherries cost four dollars.
We don't know how much the mother got and it is represented by the variable 'r'. But we do know how many pounds the dad got. He got two pounds.
We know the total cost the mom had to pay which is 4 * r and the amount the dad paid is 4 * 2 or 8.
Now we want to make an algebraic expression that represents how much more the mother paid than the father.
Final answer:
8 - (4 * r)

Answer:
answer is D
Step-by-step explanation:
pretty simple
Answer:
x: 3/4, 1 1/4, x
y:6 1/4, 7 3/4, y
Step-by-step explanation:
32 students choose a favorite topping for their slices.
Let x be the total number of students.
1/2 of the total students, or 1/2x, choose pepperoni.
1/4 of the total students, or 1/4x, choose extra cheese.
1/8 of the total students, or 1/8x, choose sausage.
4 students choose mushrooms.
We know that together, these equal the total number of students, x:
1/2x+1/4x+1/8x+4=x
We will use 8 as the common denominator:
4/8x+2/8x+1/8x+4=x
Combining like terms:
7/8x+4=x
Subtract 7/8x from both sides:
7/8x+4-7/8x=x-7/8x
4=1x-7/8x
4=1/8x
Divide both sides by 1/8:
4÷(1/8) = 1/8x÷(1/8)
4/1÷(1/8) = x
4/1×8/1 = x
32/1 = x
32 = x
