A health club charges $80 to become a member and an additional $35 per month. Assuming no other charges, what is the total cost of the first full year of membership?

500

Step-by-step explanation:

35*12+80

420+80

=500

The total cost of the first full year of membership is $500.00.

Step-by-step explanation:

m = per month

x = total cost

Equation: 80 + 35m = x

Since there are 12 months in a year and we want to figure out how much it will cost for the first full year of membership, we will substitute variable m for 12.

80 + 35(12) = x

80 + 420 = 500

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
