Question

Julie’s mom paid $2. 70 for 5 pounds of bananas at Supermart. Mario’s mom paid $2. 60

for 4 pounds of Bananas at Market One. Write a division equation for each banana

purchase, and then decide which store had the better banana price. And (then tell me the answer) and i am not in high school

Answer 1

Let’s first assign variables to the supermarkets so that we know we have two varying quantities at each store.

Supermart=x

Market One=y

We must find the unit cost of the bananas at each store, so we must create a rate:

x=2.7/5

y=2.6/4

We must divide the total cost by the number of pounds to obtain the price per banana, which is where the equations above are from.

Remember, fractions can be divided, hence why there is a fraction bar. So, we will divide the numerators by the denominators:

x=.54

y=.64

So, Supermart (x) sells bananas for 54 cents per pound, while Market One sells bananas for 64 cents per pound.

This means that Supermart has the better deal because the bananas cost less per pound.
