Question

Justin's phone had 35% battery when he

got home from school. He plugs in his
phone and the battery charges at a rate of
1.75% per minute. Write a linear equation
that models this scenario, where c
represents the charge and t represents
time.

Answer 1

I believe 35c+1.75t=100c

Explanation:

You mean, something like 35+1.75c=t

However I know that that's wrong instantly by looking at that

35c+1.75t=100c

This is how I would personally write it
