Answer:
b = 2(g + r)
Marisa used b = 8 cups of blueberries.
Step-by-step explanation:
Let g be the cups of green grapes, r be the cups of red grapes, and b be the cups o blueberries Marisa used..
then we know that
g = 1 (Marisa used 1 cup of green grapes)
r = 3 (Marisa used 3 cup of red grapes)
g + r = 4
Marisa used twice as may cups of blueberries as cups of grapes; this means
b = 2(g + r )
b = 2(4) = 8
Marisa used 8 cups pf blueberries.

Answer: The equation is $29 + x*$4.50 = $42.50, and the solution is x = 3
Step-by-step explanation:
The data we have is:
Gonzales has $42.50
He wants to buy:
a shirt that costs $29
some bracelets that cost $4.50 each.
The equation that we need to solve is:
Total cost = money that Gonzales has.
The cost is $29 + x*$4.50
where x is the number of bracelets he can buy.
The equation that we need to solve is:
$29 + x*$4.50 = $42.50
to solve it we must isolate x:
x*$4.50 = $42.50 - $29 = $13.50
x = 13.50/4.50 = 3
So we have that Mr. Gonzales can buy a total of 3 bracelets.
