Question

Juan starts with $10 in his bank and adds $5 to it every day. Maria starts with $5 in her bank and adds $10 to it every day. Please write a linear equation for Juan and one for Maria.

Answer 1

Juan- y=5x+10

Maria- y= 10x+5

In these equations y symbolises all the money they have after the x amount of days so by the x you put the amount of money they put in their bank every day and at the end add the amount of money they put in the bank at the start.
