Kelly opens a savings account with 30 dollars she got for her graduation. Every month, Kelly adds 15 dollars to the account. Represent this situation with a table, a graph, and an equation.

Let’s start by representing this situation with a table. Start by finding the amount in the savings account after 0, 1, 2, and 3 months.

To represent the situation of Kelly's savings account, we'll first populate the table with the amounts in the savings account after 0, 1, 2, and 3 months.

Initial amount: $30
Monthly deposit: $15

Let's calculate the amounts for each month:

  • At month 0:
    Amount = Initial amount = $30

  • At month 1:
    Amount = Initial amount + (Monthly deposit × 1)
    Amount = $30 + ($15 × 1) = $30 + $15 = $45

  • At month 2:
    Amount = Initial amount + (Monthly deposit × 2)
    Amount = $30 + ($15 × 2) = $30 + $30 = $60

  • At month 3:
    Amount = Initial amount + (Monthly deposit × 3)
    Amount = $30 + ($15 × 3) = $30 + $45 = $75

Now, we can fill in the table as follows:

| Time in months | Dollars in the savings account | |----------------|-------------------------------| | 0 | 30 | | 1 | 45 | | 2 | 60 | | 3 | 75 |

Now we can move on to the graph and the equation. Would you like to proceed with those?
