Ideas?

rootbeer003:

idk how to start this

dude:

Okay so we want to make an equation that represents all expenses, which is a fixed cost from the given prices?

rootbeer003:

idk because it shows 200 and 562.50

dude:

Hint: Fixed Which one has fixed before it?

rootbeer003:

200

dude:

Right \(y=mx+b\) So that is our b value In this question we are trying to find number of baskets which is our x value What is the cost per basket?

rootbeer003:

$2.50

dude:

Yes, so we have \(y=2.50x+200\) To answer the first part, we want to find the expenses for 40 baskets, so we substitute 40 in for x \(y=2.50(40)+200\)

rootbeer003:

y = 300

dude:

Right so for 40 baskets she would make $300 (You might want to reword this)

dude:

Now we have to answer part 2 If her total was $562.50, how many baskets did she buy? Do you know how to solve for this one?

rootbeer003:

562.50 = 2.50x + 200 ?

dude:

Right, now you want to solve for x

rootbeer003:

562.50 = 2.50x + 200 -200 -200 362.5 = 2.50x 145 = x
