Question

A foam toy is 2 inches wide. It doubles in size for every minute it is in water. Write an expression for the width of the toy after 5 minutes. What is the width after 5 minutes?

The answer is easier to find, but I don't know what the expression would be.

Answer 1

Ok so let's setup an equation
Where x is the time and y is the total worth slafter x minutes
y = 2*2^x
y = 2*2^5
y = 2*32
y = 64
