Chris has $400 in his bank account and he deposits
$5 per week thereafter into his
account. his brother ben has $582 in his account
and withdraws $8 per week from
his account. assuming this pattern continues, write
and solve an equation to determine how many
weeks it will take for them to have the same
amounts in their bank accounts.

400 + 5x = 582 - 8x

14 weeks

Step-by-step explanation:

Set them both up in an equation ---> x = weeks

400 + 5x = 582 - 8x

Solve

13x = 182

x = 14

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
