Question

three friends decide to increase their exercise programs at the same time. Carolyn walks 7 miles per week and decided to increase the number of miles she walks by 1.5 miles per week. Eduardo walks 3 miles per week and decides to increase the number of miles he walks by 3.5 miles per week. Kendra walks 5 miles per week and decides to increase the number of miles she walks by 3.5 miles week. Write a system of equations for this. I need help with this.

Answer 1

let's suppose x = the number of weeks

if Carolyn increases the number of miles by 1.5 per week, we can represent this as 1.5*x. she already started walking at 7 miles per week, so we would simply add 7 to the total to get y = 1.5x + 7.

repeat this same logic to the other two people. the resulting equations will form your system.
