What is the answer to the below math problem?

78000 x (1.7% x 20 years) + (1% x 10 years)

you probably meant

78000 (.017(20) + .01(10) )
which is
78000(.34+1)
= 104520

To solve this math problem, follow these steps:

1. Calculate the value of 1.7% of 78000. To do this, multiply 78000 by 1.7% (or 0.017): 78000 x 0.017 = 1326.

2. Multiply the result from step 1 (1326) by 20 years: 1326 x 20 = 26520.

3. Next, calculate the value of 1% of 78000. Multiply 78000 by 1% (or 0.01): 78000 x 0.01 = 780.

4. Multiply the result from step 3 (780) by 10 years: 780 x 10 = 7800.

5. Finally, add the results from step 2 (26520) and step 4 (7800): 26520 + 7800 = 34320.

Therefore, the answer to the math problem is 34320.
