Trudy wants to buy a television for her new apartment. The total cost is $722 including tax. She put $200 down and will make 12 monthly payments for the balance. What is the amount of each payment?

$43.5 dollars every month

Step-by-step explanation:

The cost is $722 with $200 already payed.

The amount for each monthly payment is the rest of the cost divided by the number of months.

522/12 = $43.5

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
