You are renting an apartment off-campus. There is base rent, R, in additional to a charge of $8 per unit of electricity, E. Write an equation that expresses the total, T, cost of renting this apartment.
And solve for E, if base rent is $1400 per month and you were charged $1600 this month.
T = R + 8E
E=25
