7/2x + 1/2x = 10 1/2 + 5/2x

x in (-oo:+oo)

(7/2)*x+(1/2)*x = (5/2)*x+101/2 // - (5/2)*x+101/2

(7/2)*x+(1/2)*x-((5/2)*x)-(101/2) = 0

(7/2)*x+(1/2)*x+(-5/2)*x-101/2 = 0

3/2*x-101/2 = 0 // + 101/2

3/2*x = 101/2 // : 3/2

x = 101/2/3/2

x = 101/3

x = 101/3

Step-by-step explanation:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
