Sunia is looking to join a new gym and is analyzing how much money it will cost her to be a member. The gym has a one-time startup fee of $20
and costs $60
per month to maintain membership. From this information, Sunia develops the equation and=60x+20
to represent the total cost, and
, of being a member for x
months.
PART A
Complete the table to find six solutions to Sunia's equation.
Months (x
) Total Cost (and
)
0
1
2
3
4
5
To complete the table, we need to substitute different values for x in the equation and solve for y:
For x = 0:
and = 60(0) + 20
and = 0 + 20
and = 20
For x = 1:
and = 60(1) + 20
and = 60 + 20
and = 80
For x = 2:
and = 60(2) + 20
and = 120 + 20
and = 140
For x = 3:
and = 60(3) + 20
and = 180 + 20
and = 200
For x = 4:
and = 60(4) + 20
and = 240 + 20
and = 260
For x = 5:
and = 60(5) + 20
and = 300 + 20
and = 320
The completed table is as follows:
Months (x) Total Cost (and)
0 20
1 80
2 140
3 200
4 260
5 320
