Jackie needs to save $125 to go to a concert. He has saved $35. He makes $7.50 an hour at his job. Let x representing the number of hours.

Which equation and solution can be used to show how many hours jackie must work in order to have enough money to go to the concert?

A. 125x + 35 = 750; x = 5.75
B. 35 - 7.5x = 125; x = 6
C. 7.5x + 35 = 125; x = 12
D. 35x + 125 = 750; x = 18

Answer is C

Step-by-step explanation:

First Jackie needs to save $125

y = 125

He already saved $35, this is our constant

He makes $7.50 an hour on his job,

Our variable x is hours

125 = 7.50x + 35

If we solve for x, we get x = 12

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
