Help

Answer 8

lets say Mahal bought "x" pounds of grapes, ok?

Answer 9

Ok

Answer 10

\(\large\color{black}{ \displaystyle 2.99x }\)
would then be the cost of x pounds of grapes.

Answer 11

Ok

Answer 12

He pays 20, and the cost is 2.99x

so what is then the change?

Answer 13

(Think about it, if I paid x dollars and the cost was y, then the change is x-y)

Answer 14

Ok lemme see

Answer 15

2.99 - 20?

Answer 16

The change is

"Paid Amount" - "Price"

correct?

Answer 17

What was my "price" and what was my "paid amount" ?

Answer 18

Mmh

Answer 19

price is 2.99 and paid with 20

Answer 20

So the change is?

Answer 21

2.99 - 20 = 17.01?

Answer 22

but wait, the price is not exactly that.
The price is 2.99x

Answer 23

Amount Paid - Price = Change

Answer 24

Change is 17.01

Answer 25

20 - 2.99x

this is the change when you pay with a 20 dollar bill,
for x pounds of graphs (where each pound of graphs costs 2.99 dollars)

Answer 26

Ok

Answer 27

Dont have much time, hurry pls.

Answer 28

Well, in the problem, they chose p to denote the number of pounds and not the x.
So then you should say that the change is:

20-2.99p

Answer 29

that is it, btw

Answer 30

so its 20 - 2.99?
or 17.01?

Answer 31

I kinda dont get it
