Question

write an equation to represent the relationship, and find the amount of peanut butter used to make 25 cracker packages. the table is peanut butter (tbsp) 1/2,5/8,3/4,7/8, the bottom is cracker packages 2,2 1/2,3,3 1/2.

Answer 1

We are given 4 points.

`((1)/(2),2)`

`((5)/(8),(5)/(2))`

`((3)/(4),3)`

`((7)/(8),(7)/(2))`

Using this, we can make an equation.

`y=4x`

I got
`m=4` by using the slope formula.

`m=(2.5-2)/(0.625-0.5)`

`m=(0.5)/(0.125)`

`m=4`

So the equation we have is
`y=4x`

Now, we can solve for how much peanut butter is used to make 25 packages by plugging in 25 for
`y`, which is the number of cracker packages.

`25=4x`

`x=(25)/(4)`

We need to use
`(25)/(4)` teaspoons of peanut butter to make 25 packages of crackers.

Hope this helps.

頑張って!
