The complete table is shown
a 0 1 2 3 4
b 0 13 26 39 52
The graph is continuous; because the data is continuous , so, It involves connected lines
b. When the coach spends $ 117. She bought 9 basketballs
How to complete the table
The table is completed by substituting the different values of b to solve for a.
According to the problem, the expression is a = 13b
For b = 0, a = 13 * 0 = 0
For b = 1, a = 13 * 1 = 13
For b = 2, a = 13 * 2 = 26
For b = 3, a = 13 * 3 = 39
For b = 4, a = 13 * 4 = 52
When the coach spends $ 117 the number of balls bought is solved below
117 = 13b
b = 117 / 13
b = 9
