Davion Valenzuela · Answer 1

The answer is 450 that's how much it'll be if they had the same

Caren · Answer 2

Both accounts will have $450

Step-by-step explanation:

Tina y = 25x+220

Cliff y = 35x+100

we can use substitution to solve this problem so the formatting would be:

25x+220=35x+100

subtract 25x from both sides

220=10x+100

Subtract 100 from both sides

120=10x

Divide both sides by 10

12=x

now that we have an x value we can plug it into either equation.

y=100+35 (10)

y=100+350

y=450
