Question

TRYING TO GET A UNDERSTANDING CAN YOU HELP ME WITH THE FIRST TWO PROBLEMS PLEASE??
The function A(t) =7t represents the total amount of money in dollars Carmen earns babysitting as function of time in hours. solve each function for the input given the OUTPUT value.

1. A(t) = 14
2. A(t) = 35

Answer 1

got it

A(t)=7t
so for a certain value of t, we get an output

1.
ok, so when t= some value, then A(t)=14
since A(t)=7t we do
7t=14, find t
divide both sides by 2
t=2
so it would be A(2)=14
t=2


2.
same thing
A(t)=7t
and A(t)=35
find t when 7t=35
divide both sides by 7
t=5
