one day you decide to get stronger by doing pushups. you start by doing 5 pushups on the first day. then you increase it to 10 on the second day. then 15 on the next day and you continue this pattern for a week. write an equation that relates the number of pushups y to the number of days x during the week

a. x - y =5
b. x + y=5
c. y=5x
d. x=5y

c. y=5x

This equation represents the pattern of doing 5 more pushups each day during the week. The number of pushups (y) is equal to 5 multiplied by the number of days (x).
