51
+29

1+9=10

Carry the 1 over the 5 and leave the 0 below the 9

Then it’s 5+2=7 plus that one above the five making it 8

So the answer is 80

Julie wants to purchase a new home in six years. She thinks that she can purchase a nice home in a good neighborhood for $60,000

MrMuchimi

Answer:

$208.33

Step-by-step explanation:

Julie has to make the down payment which is 25% of $60000 after saving for 6 years.

Therefore, Julie has to save a total of $60000 \times \frac{25}{100} = 15000$ dollars.

And Julie has to save it for the duration of 6 years i.e. (6 × 12) = 72 months.

Hence, Julie has to save $\frac{15000}{72} = 208.33$ dollars every month to make the down payment after 6 years. (Answer)
