Jessica will have saved $175, and Ron will have saved $165.
Step-by-step explanation:
Jessica starts out with $50. She adds $25 each week, and it's asking how much money she would have in 5 weeks. So, you multiply $25 by 5 to get $125. Then, you add $50 to that to get $175. Same thing for Ron. Multiply $25 by 5 to get $125, but this time add $40 to it to get $165.
Jessica starts with $50 so put that aside and then it says that she adds $25 EVERY WEEK so how much is she going to have in 5 weeks? 5 x $25 is $125 and now add the $50 which will equal $175
In Ron is the same thing but rather than adding $50 add $40 and it will equal $165
If you look at both equations they both have 2x in them. This makes it easier to eliminate x. To eliminate x we must subtract the second equation from the first (because 2x - 2x = 0).
