your mom gives you $5 for a weekly allowance. Your grandpa gives you an amount per chore that you do for him. After doing 7 chores for your grandpa, you have raised 15.50 total. Write an equation that represents the amount of y of money you have raised after x chores

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
