I really need help please!! <br><br> Please show work!! Will mark brainliest!!
Setler [38]

Answer:

A) Lifetime: 200+15x

Health Bridge: 50+30x

B.1) Yes, they are both the same price after 10 Months at an amount of $350

B.2) Lifetime gym would be cheaper by $30

C) Health Bridge Gym because it is $60 less

D) Lifetime Gym

Step-by-step explanation:

A) 200=Initial Fee___15=Monthly Cost___x=Months

50=Initial Fee___30=Monthly Cost___x=Months

--------------------------------------------------------------------------------------------------------------

B.1) 200+15(10)=350

50+30(10)=350

--------------------------------------------------------------------------------------------------------------

B.2) 200+15(12)=$380

50+30(12)=$410

--------------------------------------------------------------------------------------------------------------

C) 200+15(6)=290

50+30(6)=230

--------------------------------------------------------------------------------------------------------------

Lifetime Gym's initial fee is greater than Health Bridge's fee but without exceeding $500, you are able to go to the gym for 20 months rather than 15 months using Health Bridge's plan.

D)200+15(20)=$500

50+30(15)=$500

--------------------------------------------------------------------------------------------------------------
