To find the sum of 1/2 of #3.50, 1/3 of #4.20, and 1/4 of 84k, we need to calculate each value separately and then add them together.
First, let's find 1/2 of #3.50. To do this, we multiply #3.50 by 1/2:
#3 50 * 1/2 = #175
Next, let's find 1/3 of #4.20. To do this, we multiply #4.20 by 1/3:
#4.20 * 1/3 = #1.40
Finally, let's find 1/4 of 84k. To do this, we multiply 84k by 1/4:
84k * 1/4 = 21k
Now, we add the three values together to find the sum:
#1.75 + #1.40 + 21k = #3.15 + 21k
Please note that the result is a combination of a monetary value (#3.15) and a numerical value (21k).
So, the sum of 1/2 of #3.50, 1/3 of #4.20, and 1/4 of 84k is #3.15 + 21k.
