Ian is saving up to buy a new baseball glove. Every month he puts $10 into a jar. Which type of function best models the total amount of money in the jar after a given number of months?

1) linear 2) exponential 3) quadratic 4) square root
1) linear 2) exponential 3) quadratic 4) square root
The function which represents the given model is a linear function.
Assume y to be the total amount of money after a given number of months, and x to be the initial amount. The money increases $10 per month.
y = x + 10 will represent this function. Plotting this function will result in a straight line.
CHECK:
If x = 0, then y = 10 (first/initial month)
If x = 1, then y = 20 (second month)
If x - 2, then y = 30 (third month)
