Given:
- Jim's starting amount: $510
- Jim's monthly deposit: $80
- Ashley's starting amount: $590
- Ashley's monthly deposit: $60

(a) To find the amount of money in each account after $$ x $$ months, we can use the formula for the amount of money in a savings account:
$$ \text{Amount} = \text{Starting Amount} + (\text{Monthly Deposit} \times \text{Number of Months}) $$

For Jim's account:
$$ \text{Amount in Jim's account} = 510 + (80 \times x) $$

For Ashley's account:
$$ \text{Amount in Ashley's account} = 590 + (60 \times x) $$

(b) To find when the two accounts would have the same amount of money, we need to set the expressions for the amount of money in each account equal to each other and solve for $$ x $$:
$$ 510 + (80 \times x) = 590 + (60 \times x) $$

Let's solve this equation to find the value of $$ x $$ when the two accounts would have the same amount of money.
Solve the equation by following steps:
- step0: Solve for $$x$$:
  $$510+80x=590+60x$$
- step1: Move the expression to the left side:
  $$80x-60x=590-510$$
- step2: Add and subtract:
  $$20x=590-510$$
- step3: Add and subtract:
  $$20x=80$$
- step4: Divide both sides:
  $$\frac{20x}{20}=\frac{80}{20}$$
- step5: Divide the numbers:
  $$x=4$$
The value of $$ x $$ when the two accounts would have the same amount of money is $$ x = 4 $$ months.
(a) - Jim's account: $$ 510 + 80x $$ - Ashley's account: $$ 590 + 60x $$ (b) When the two accounts have the same amount of money: $$ 510 + 80x = 590 + 60x $$
