Write code and solve in Matlab

Imagine that you are a proud new parent. You decide to start a college savings plan now for your child, hoping to have enough in $18$ years to pay the sharply rising cost of eductation. Suppose that you have $$1000$ to get started and that each month you can contribute $$100.$ Suppose also that the interest rate is $0\mathrm{.}5\%$ each month. Because of interest payments and your contribution, each month your balance will increase in accordance with the formula

New balance $=$ old balance $+$ interest earned $+$ your contribution

$Or,$ similarly,

Balance $(i+1)=$ Balance $(i)**(1+IR)+$ Contribution

Use a for loop to find the amount in the savings account at the end of each month for the next $18$ years. Plot the balance in the account as a function of time.
