Cecilia set a goal to raise $2,500.00 for her favorite charity this year. She has decided to participate in a walk-a-thon to help her reach her goal. She found 70 sponsers and each sponser has agreed to give her $0.50 for each mile that she walks in the walk-a-thon. Which of the following functions shows the remaining money that she needs to raise this year, G, as a function of the number of miles that she walks in the walk-a-thon, m? A.
G = 2,500 - 35m
B.
G = 2,500 - 350m
C.
G = 2,500 - 3.5m
D.
G = 2,500 - 5m

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

answer: im sorry i dont get it

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
