Answer:
6 weeks
Step-by-step explanation:
You can use linear equations to find this out.
y is the total amount saves, x is the number of weeks.
Jade's equation: y = 5x + 0 (the 5 is how much she will save each week, the 0 is how much she has now, or the initial value.)
Enrique's equation: y = 3x + 12 (the 3 is how much he will save each week, the 12 is how much he has now, or the initial value.)
You can set up a table, or you could enter it in your calculator.
After entering the equations in my calculator, I found that the x value of 6 was when both equations had the same y value. So after 6 weeks, both of them had saved 30 dollars.
