Step-by-step explanation:
Have A Blessed Day :)
From the information given, she owes her parents a total of $1854.
She will take a period of 18 months to repay the whole loan.
We first find out the how much is each installment per month.
We divide the whole amount by 18 months so 1854/18 = $103
If she pays 103 dollars per month, then at one year (12 months) she would have paid: 103 × 12 = 1,236 dollars.
She would owe 1854 - 1236 = 618
There she would still be owing her parents $ 618 after one year.
-18 - 30 = -48

Answer:
Multiply the ones. 9 times 83 is 747. Multiply the tens. 30 times 83 is 2,490. Add the products to get 3,237.
The rest of the question:
Which gives the correct order of steps needed to multiply the problem below? "83x39
"
The steps to multiply 83x39
1) multiply the ones 9 times 83 = 9 times 3 + 9 times 80 = 27 + 720 = 747
2) multiply the tens 30 times 83 = 30 times 3 + 30 times 80 = 90 + 2400 = 2490
3) add 747 and 2490 = 747 + 2490 = 3,237
According to the previous steps, the answer is option 3
Multiply the ones. 9 times 83 is 747. Multiply the tens. 30 times 83 is 2,490. Add the products to get 3,237.
