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

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
