1. Write an expression to find the cost of 2 pounds of apples and 1 head of lettuce from grocery store #1.
Let the cost of 1 pound of apples be represented by A and the cost of 1 head of lettuce be represented by L.
Therefore, the expression to find the cost of 2 pounds of apples and 1 head of lettuce from grocery store #1 would be:
2A + L
2. Write an expression to find the cost of 2 pounds of apples and 1 head of lettuce from grocery store #2.
Let the cost of 1 pound of apples from grocery store #2 be represented by A2 and the cost of 1 head of lettuce from grocery store #2 be represented by L2.
Therefore, the expression to find the cost of 2 pounds of apples and 1 head of lettuce from grocery store #2 would be:
2A2 + L2
Head of lettuce Krogers Cost: $1.79
Head of Lettuce Publix Cost: $1.88
Gallon of milk Krogers Cost: $3.39
Gallon of milk Publix Cost: $3.22
A dozen eggs Krogers Cost: $2.29
A dozen eggs Publix Cost: $2.24
A pound of apples Krogers Cost: $2.29/pound
A pound of apples Publix Cost: $2.45/pound
Frozen pizza Krogers Cost: $8.49
Frozen pizza Publix Cost: $9.24
1. Write an expression to find the cost of 2 pounds of apples and 1 head of lettuce from grocery store #1(Kroger)
Answer: 2A + L
2. Write an expression to find the cost of 2 pounds of apples and 1 head of lettuce from grocery store #2 (Publix.)
Answer: 2A2 + L2
3. If you have $20 to spend, can you buy 3 dozen eggs and a frozen pizza from either store? Which one(s)?
To determine if you can buy 3 dozen eggs and a frozen pizza with $20 from either store, we need to calculate the total cost for each item at each store.
Kroger:
Cost of 3 dozen eggs at Kroger: 3 * $2.29 = $6.87
Cost of frozen pizza at Kroger: $8.49
Total cost at Kroger: $6.87 + $8.49 = $15.36
Publix:
Cost of 3 dozen eggs at Publix: 3 * $2.24 = $6.72
Cost of frozen pizza at Publix: $9.24
Total cost at Publix: $6.72 + $9.24 = $15.96
Comparing the costs, the total cost at Kroger is $15.36, which is less than $20, so you can buy 3 dozen eggs and a frozen pizza from Kroger with $20. However, the total cost at Publix is $15.96, which is more than $20, so you cannot buy 3 dozen eggs and a frozen pizza from Publix with $20.
4. How many whole gallons of milk can you buy for $14 at each store? Remember, you can't buy part of a gallon. Write and solve an equation to find your answer.
To calculate the number of whole gallons of milk you can buy for $14 at each store, we need to divide the total amount of money by the cost of one gallon of milk at each store.
Let's define some variables:
Let G1 be the number of whole gallons of milk you can buy from Kroger.
Let G2 be the number of whole gallons of milk you can buy from Publix.
Let C1 be the cost of one gallon of milk at Kroger ($3.39).
Let C2 be the cost of one gallon of milk at Publix ($3.22).
Let M be the total amount of money you have ($14).
Now, we can write and solve separate equations for each store:
From Kroger: G1 * C1 = M
From Publix: G2 * C2 = M
For Kroger:
G1 = M / C1
G1 = 14 / 3.39
G1 ≈ 4.13 (round down to 4 gallons since you can only buy whole gallons)
For Publix:
G2 = M / C2
G2 = 14 / 3.22
G2 ≈ 4.35 (round down to 4 gallons since you can only buy whole gallons)
Therefore, you can buy 4 whole gallons of milk for $14 at both Kroger and Publix.
