1. The 7th grade class is selling boxes of votive candles as a fundraiser. The first box purchased costs $14.00, and each additional box costs $10.00.
1.a Between the number of additional boxes of candles purchased and total money, is it linear?
1.b Make an equation that relates the total money spent on boxes of candles(c), to the number of additional boxes purchased (b).
1.c Using the equation from part (b), the total money spend on 3 boxes of candles during this fundraiser would be $?

to find the unit price of an object, you divide the price by object. you are trying to find out how much an object cost per unit.

for instance, lets say you have 50lb of ice cream(object) that cost 8.00 dollars(price). to find the unit cost, we take the 8.00 and divide it by 50, which will give us .16 cents per pound. we can check this by multiplying .16 by 50 = 8.00

so

object = e2

price = d2

unit price = c2

formula for c2:

=d2 / e2

so in my example about ice cream, we would have the following.

e2 = 50

d2 = 8.00

c2 formula:

=d2 / e2

-x represents miles per gallon

-y represents cargo weight

-vehicle traveled an average of 5.3 miles per gallon(x1) with load of 22 tons (y1)

- vehicle traveled an average of 6.3 miles per gallon( x2) with load of 18 tons( y2)

so, equation now becomes

so, option a) is correct
