Question

Regina has $25 to buy groceries. She needs 3 cans of dog food, a gallon of milk, 5 pounds of chicken, a box of cereal, and 6 rolls of paper towels. The prices of the items are as follows: dog food—$1.50 a can; milk—$4 a gallon; chicken—$1.55 a pound; cereal—$2.75 a box; paper towels—99 cents a roll. Will Regina have enough money for all the items she needs? If not, how much more will she need? (Note: Remember that there are 100 cents in a dollar.)

Answer 1

Regina has enough money to buy all the items she needs 

3 cans of dog food = 1.50*3 = 4.50
1 gallon of milk = 4.00*1 = 400
5 pounds of chicken = 1.55*5 = 7.75
1 box of cereal = 2.75*1 = 2.75
6 rolls of paper towels = .99*6 = 5.94

If you add all those together it equals 24.94 leaving 6 cents in change

4.50 + 4.00 + 7.75 + 2.75 + 5.94 = 24.94$

Answer 2

Prices of food:
Dog food- $1.50 a can
Milk- $4 a gallon
Chicken- $1.55 a pound
Cereal- $2.75 a box
Paper Towels- $0.99 a roll

Lets begin :)

She needs:
1. 3 cans of dog food
2. 1 gallon of milk
3. 5 lbs of chicken
4. 1 box of cereal
5. 6 rolls of paper towels

Its really simple (the numbers below match the items above for the total prices)
You will multiply each item by the price it is listed as and you will get the following prices for each item.

Total for all her items:
1. $4.50 
2. $4.00 
3. $7.75 
4. $2.75 
5. $5.94 

You would then add all of the prices together

Total price of all the items would be:

$24.94

She has just enough money to buy all of her items.
