Question

at a farmers market oranges sell for $5 per bag and apples sell for $3 per bag. Marc buys 7 bags of fruit for $29. How many bags of each type of fruit did he buy?

Answer 1

Answer:

Step-by-step explanation:

Find out how many bags of each type of fruit did jordan buys .

To prove  

let us assume that the number of orange bags jordan buys be = x  

let us assume that the number of apples bags jordan buys be = y

As given  

At a farmers market, oranges sell for $5 per bag and apples sell for $3 per bag.  

Jordan buys 7 bags of fruit for $31.

Than the equation becomes

x + y = 7  

5x + 3y  = 31  

Multiply x + y = 7 by 3 and subtracting from 5x + 3y  = 31 .

5x - 3x + 3y - 3y = 31 -21

2x = 10

x = \frac{10}{2}

x = 5  

put this in the x + y = 7 .

5 + y = 7

y = 7-5  

y =  2  

Therefore the number of oranges bags jordan buys be 5 .

the number of apples jordan bags buys be 2.

Hence proved
