Question

Complete the chart below for this word problem.

Canadian Tire is selling coffee mugs. A coffee mug costs $5 and each day the price increases by $2. (The algebraic equation for this: 5+2x)

Fill out the variable chart below for graphing. The days are on the x-axis and the cost is on the y-axis.

Answer 1

The y-values from top to bottom are;

3, 5 , 7, 9, 11, 13, 15

Explanation:

Here, we want to fill out the given table

Let us have an equation linking x and y

From the question, we can have this as;

y = 5 + 2x

When x = -1

y = 5 + 2(-1) = 3

when x = 0

y = 5 + 2(0) = 5

when x = 1

we simply add 2 to the previous

= 5 + 2 = 7

when x = 2

= 7 + 2 = 9

when x = 3

= 9 + 2 = 11

when x = 4

= 11 + 2 = 13

when x = 5

y = 13 + 2 = 15
