Question

Rachel opens a savings account with $332. She saves $11 a week. Write an equation modeling how much she has after x months?

Answer 1

we assume she adds 11 dollars per week

so


y=mx+b
y=amount
m=amount added per week
b=amount started, that is at x=0 or week 0

y=11x+332 is the equation
or
f(x)=11x+332

Answer 2

332+11w=x
W means a week
