Connor has seven more nickels than dimes and twice as many quarters as dimes. If he has $6.20, how many nickels does Connor have?

(A) Your monthly mortgage payment will be $1,496.32. To calculate this, we can use the formula: M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1] where M is the monthly payment, P is the loan amount, i is the interest rate per month (which is 7% divided by 12 months), and n is the number of months (which is 30 years times 12 months per year). Plugging in the numbers we get: M = 225000 [ 0.00583(1 + 0.00583)^360 ] / [ (1 + 0.00583)^360 – 1] M = $1,496.32 (B) The interest portion of your first month's payment will be $1,218.75. To find this, we can multiply the loan amount by the monthly interest rate: i = 0.07 / 12 = 0.00583 Interest portion = loan amount ? monthly interest rate = 225,000 ? 0.00583 = $1,218.75 (C) The principal portion of your first month's payment will be $277.57. This can be found by subtracting the interest portion from the total monthly payment: Principal portion = monthly payment – interest portion = $1,496.32 – $1,218.75 = $277.57
