4.) Together Alice & Mindy have saved $490 for a trip this summer. Amy has saved $54 more than Mindy. How much has each person
saved? Write a system & use substitution to solve.

Mindy=191

Amy=299

Step-by-step explanation:

first you want to divide $490 in half to see what each person has. Thats 245 and since Amy has $54 more, you minus 54 from 245 to get 191. So while Mindy has 191, Amy has 299

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
