Question

WILL MEDAL IF RIGHT
write an equation that represents the following problem:
There are two cell phone plans available from cell phones R us company. Plan A charges $35 per month plus $0.05 for every text message. Plan B charges $50 plus $0.01 for every text message . How many text messages do you need to send in order for plan a to cost the same as plan b
A. 35 + 0.05m = 50 + 0.01m
B. 35 + 5m = 50 + m
C. 35 + m = 50 + 5m
D. 50 + 0.05m = 35 + 0.01m

Answer 1

i will help again @Mavckenzie

Answer 2

Ok

Answer 3

50+.01t<35+.05t subtract .05t from both sides

50-.04t<35 subtract 50 from both sides

-.04t<-15 divide both sides by -.04 (and flip sign as rule because of division by a negative number)

t>375

So plan B is cheaper than plan A when you send more than 375 texts... 35+0.05t>50+50+0.01t @Mavckenzie

Answer 4

did it help ??? @Mavckenzie

Answer 5

not really because its not about it being bigger (< >) its about what makes plan a equal to plan b
