Answer:
500
Step-by-step explanation:
10*1*22=220
7*4*10=280
220+280=500
Function F goes in the first one, G goes in the second one, and H goes in the last one. Hope this helps :)

![\boxed{ \bold{ \huge{ \boxed{ \sf{a = - 1.75}}}}}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%20%5Cbold%7B%20%5Chuge%7B%20%5Cboxed%7B%20%5Csf%7Ba%20%3D%20%20-%201.75%7D%7D%7D%7D%7D)
Step-by-step explanation:
![\sf{ \frac{ - 3}{4} = \frac{3a}{7} }](https://tex.z-dn.net/?f=%20%5Csf%7B%20%5Cfrac%7B%20-%203%7D%7B4%7D%20%20%3D%20%20%5Cfrac%7B3a%7D%7B7%7D%20%7D)
Do cross multiplication
![\dashrightarrow{ \sf{3a \times 4 = 7 \times ( - 3)}}](https://tex.z-dn.net/?f=%20%5Cdashrightarrow%7B%20%5Csf%7B3a%20%5Ctimes%204%20%3D%207%20%5Ctimes%20%28%20-%203%29%7D%7D)
![\longrightarrow{ \sf{12a = - 21}}](https://tex.z-dn.net/?f=%20%5Clongrightarrow%7B%20%5Csf%7B12a%20%3D%20%20-%2021%7D%7D)
Divide both sides by 12
![\longrightarrow{ \sf{ \frac{12a}{12} = \frac{ - 21}{12}}}](https://tex.z-dn.net/?f=%20%5Clongrightarrow%7B%20%5Csf%7B%20%5Cfrac%7B12a%7D%7B12%7D%20%20%3D%20%20%5Cfrac%7B%20-%2021%7D%7B12%7D%7D%7D%20)
Calculate
![\longrightarrow{ \sf{a = - 1.75}}](https://tex.z-dn.net/?f=%20%5Clongrightarrow%7B%20%5Csf%7Ba%20%3D%20%20-%201.75%7D%7D)
Hope I helped!
Best regards! :D
X equals the number of aerobics classes.
We create an equation to solve for x.
Member Cost = Nonmember Cost
8 + 2x = 0 + 4x
Solve for x:
8 + 2x = 4x (subtract 2 from both sides)
8 = 4x - 2x (combine like terms)
8 = 2x
4 = x
For 4 aerobics classes, the cost of members and nonmembers will be the same.
