A) 110 - (3 × 14x) = 68
B) 3×14 is 42 so he spent $42 in two weeks 42+68= 110 so he had $110 to begin with
C) he will run out of money in about 22 days (22.6666666667)
C is the answer . 81/3 = 27 and 54/2= 27
There are 8 pints in a gallon, so there are 16 pints in two gallons.
We know, interest value = P * R * T /100
Here, I = 420
R = 7%
T = 1
Substitute their values,
420 = P * 7 * 1 /100
P = 420*100 / 7
P = 60*100
P = 6000
In short, Your Answer would be Option D) $6,000
Hope this helps!
