Question

(a) Write an equation that could be used to answer the question above.

Answer 1

The linear equation that can be used to represent the situation using 9, w and 163 is 9w + 63 = 198

The solved equation to find the number of weeks is w = 15

What is a linear equation?

Linear equation are equation in which the highest power of the variable is equals to 1.

Suzan is saving money to buy a bike . She already have $63 and is going to save an additional $9 per week. The cost of the bike is $198.

Let

w = number of weeks

The linear equation that can be used to represent the situation using 9, w and 163 is as follows:

using the slope-intercept form,

y = mx + b

where

m = slope

b = y-intercept

Therefore,

• 9w + 63 = 198

The solved equation to find the number of weeks is as follows:

• 9w = 198 - 63
• 9w = 135
• w = 135 / 9
• w = 15
