ann pays 300 for membership to a local gym. she is allowed to bring one guest on any visit. John pays Ann 5 to go to the gym wit
klemol [59]

Answer:

The expression represents Ann's membership cost as a function of how many times she brings John along. For t = 5 the cost is 275, for t = 10, the cost is 250 and for t = 20 the cost is 200.

Step-by-step explanation:

The expression "300 - 5*t" represents the cost of Ann's membership plan on the local gym, where "t" is the number of visits John pays Ann. This means that the more times John goes to the gym with Ann, the less is her cost to pay the membership.

For t = 5:

cost = 300 - 5*t\\cost = 300 - 5*5 = 275

For t = 10:

cost = 300 - 5*t\\cost = 300 - 5*10 = 250

For t = 20:

cost = 300 - 5*t\\cost = 300 - 5*20 = 200

There are a total of 84 students in the robotics club and the science club. The science club has 12 more students than the robot
Dafna11 [192]

Answer:

48 students in science

Step-by-step explanation:

Let r = students in robots club

s = students in science club

r+s = 84

s = r+12

Substitute the second equation into the first

r+(r+12) = 84

Combine like terms

2r+12 = 84

Subtract 12 from each side

2r = 84-12

2r = 72

Divide by 2

r = 72/2 = 36

We need to find s

s = r+12

s = 36+12

s = 48

There are 48 students in the science club
