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. how many bags of each type of fruit did she buy?

Answer

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 = 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

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
