Question

Lucy pays $224 in advance for her gym membership. Each time she visits the gym, $7 is deducted (-) from her account. Write an equation in slope-intercept form (y = mx +b) that represents the value of her account after x number of visits.

Answer 1

The equation that represents the value of Lucy's account after x number of visits is y = 224 - 7x. To find the value of Lucy's account after a specific number of visits, substitute the value of x into the equation and solve for y.

Step-by-step explanation:

The equation that represents the value of Lucy's account after x number of visits is:

y = 224 - 7x

where:

• y represents the value of Lucy's account
• x represents the number of visits
• 224 represents the initial amount in Lucy's account
• 7 represents the amount deducted from Lucy's account per visit

To find the value of Lucy's account after a specific number of visits, substitute the value of x into the equation and solve for y.
