This equation shows how the total distance Jackie has walked depends on the number of trips she has made to school. d = 1.9t + 62

The variable t represents the number of trips she has made, and the variable d represents the total distance walked in kilometers. How many trips will Jackie have to make in all to walk a total of 88.6 kilometers?

I have uh- 3 minutes to answer this-

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
