The complete statement is: Health Club A costs $30 in monthly membership fees more each month than Health Club B.
How to calculate monthly cost by applying slope-intercept equation formula?
If an equation is written in slope-intercept form as y = mx + b, m stands for the slope or unit rate while b stands for the y-intercept or initial value.
In this case, the one-time signup fee each club signs represents the initial value or y-intercept (b), y represents what he club charges in total, x represents the number of months, and the coefficient of x (m) represents the monthly charge (unit rate).
Here, we are only concerned about the unit rate or monthly charge since we are asked about the monthly membership fee.
Health Club A's monthly cost is given by the equation y = 59x + 50, this means that the unit rate or monthly membership fee is $59.
Health Club B charges a flat $29 per month. This is also its unit rate.
The difference between both is: 59 - 29 = $30. Thus, in terms of monthly membership fees, health club A cost $30 each month than health club B.
Complete Question:
