Patrick owns an apartment building. He knows that the money he earns in a month depends on the rent he charges. The relationship can be modelled by E=1/50R(1650-R), where E is Patrick's monthly earnings, in dollars, and R is the amount of rent, in dollars, he charges each tenant. if Patrick wants to earn at least $13000, between what two values should he set the rent?

E=13,000 andE=1/50R(1650-R)

0.02R(1650-R)=13000

(0.02R)(1650)-0.02R²=13000

0.02R²-33R+13000=0

R2-1650R+650000=0
