Tina has $220 in her account. cliff has $100 in his account. starting in july, tina adds $25 to her account on the first of each month, while cliff adds $35 to his. how many dollars will they have in their accounts when the amounts are the same

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
