Question

A grocery store sells a bag of 4 oranges for $2.96. How much would it cost for 11 oranges?

Answer 1

2.96 / 4 = x / 11

Can you solve for x and answer?

Answer 2

the cost per orange here is

$2.96 / 4 = $0.74 per orange

from there then you can multiply by 11 to find the total cost of 11 oranges

$0.74/orange x 11 oranges = $8.14

Answer 3

Problem

A grocery store sells a bag of 4 oranges for $2.96. How much would it cost for 11 oranges?

Step 1

Since we know that the price for a bag of four oranges is $2.96, we can divide this price by the number of oranges to get the price for just one orange.

$2.96 / 4 oranges = 0.74¢ / orange

Step 2

Now that we know each orange costs 74 cents, we can multiply that cost by the amount of oranges we want - in this case, we want 11 oranges.

0.74¢ × 11 oranges = $8.14

Therefore, we would have to spend 8.14$ in order to get 11 oranges.

Solution

11 oranges would cost 8 dollars and 14 cents.

Answer 4

The easiest way to start problems like this is to write down what you know and what you are looking for.

1 bag = 4 oranges = $2.96

11 oranges = how much money?

Now you can use what you know and what you are solving for to find a relationship. In this case, the easiest way to solve the question is by finding the price of one orange.

Price of one orange = $2.96/4 oranges = $0.74

Then you can multiply the price of one orange by 11 to find the price of 11 oranges.

Price of 11 oranges = $0.74 x 11 oranges = $8.14.

Answer 5

O is number of oranges.

4O = 2.96

11O = x

Cross Multiply

4x = 2.96*11 = 32.56

x = 8.14
