To calculate Lamar's new mortgage payment, we first need to know what his regular payment is. Let's call his regular payment "P".
Then, his new payment will be 30% more than his regular payment, which means he will pay:
P + 0.3P = 1.3P
So Lamar's new mortgage payment will be 1.3 times his regular payment.
To calculate how much he will pay in 6 months, we need to multiply his new payment by the number of payments he will make in that time period, which is 6. Therefore, he will pay:
6 x 1.3P = 7.8P
So Lamar will pay 7.8 times his regular mortgage payment in the next 6 months.
