23. Number of tickets. Total Cost
2. $7.
4. $14
6. $21
These are all pretty much the same type of linear problem .......let x be the Number of Tickets and y be the Total Cost
Note that as y changes by $7, x changes by 2.....so...the slope of our line = 7/2
And letting one point be (2, 7)....we have the following equation :
y = (7/2)(x - 2) + 7
24, 25 and 27 are similar to 23
26. Total cost. Change from $10
$10.00. $0
$9.00. $1.00
$7.50. $2.50
This one is a little tricky......let the Change from $10 be y and the Total Cost = x
The function that models this is : y = 10 - x
28. Miles traveled. Miles remaining
0. 500
125. 375
350. 150
Let the Miles Remaining be y and the Miles Traveled
This is similar to 26.....the function that models this is y = 500 - x
