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 y = 60x + 20 to represent the total cost, y, of being a member for x months.
PART A.
Complete the table to find six solutions to Sunia's equation.
Months (x) 0,1,2,3,4,5
Total cost (y) enter answer, enter answer, enter answer, enter answer, enter answer, enter answer
To find the total cost (y) for each month (x), we can substitute the values of x into the equation y = 60x + 20.
Using the given months: 0, 1, 2, 3, 4, 5
For x = 0:
y = 60(0) + 20
y = 0 + 20
y = 20
For x = 1:
y = 60(1) + 20
y = 60 + 20
y = 80
For x = 2:
y = 60(2) + 20
y = 120 + 20
y = 140
For x = 3:
y = 60(3) + 20
y = 180 + 20
y = 200
For x = 4:
y = 60(4) + 20
y = 240 + 20
y = 260
For x = 5:
y = 60(5) + 20
y = 300 + 20
y = 320
Completing the table, we get:
Months (x) Total cost (y)
0 20
1 80
2 140
3 200
4 260
5 320
