Simone paid $17 for an initial year's subscription to a magazine. The renewal rate is $8 per year. This situation can be represented by the equation
y = 8x + 17,
x (number of years renewed) | 0 | 1 | 2 | 3 | 4 |
y (total cost in dollars) |
where x represents the number of years the subscription is renewed and y represents the total cost, in dollars.
The problem says that y = 8x + 17 .
To find y when x = 0 , plug in 0 for x and solve for y .
When x = 0 , y = 8(0) + 17 = 0 + 17 = 17
When x = 1 , y = 8(1) + 17 = 8 + 17 = 25
When x = 2 , y = 8(2) + 17 = 16 + 17 = 33
When x = 3 , y = 8(3) + 17 = ...can you finish this?
And this is how to fill in the table...
_x (number of years renewed)__ | 0 | 1 | 2 | 3 | 4 |
_y (total cost in dollars) | _17_ | _25_ | _33_ | ____ | ____ |
Can you finish the last two?
