Question 3 • Financial Math

Given the linear functions f of x is equal to 0 point 5 x plus 0 point 7 5 and g of x is equal to 0 point 3 3 x minus 0 point 8 3 , what is f of x minus g of x ?

Answer
A
0 point 1 7 x plus 1 point 5 8
B
0 point 8 3 minus 0 point 0 8
C
0 point 8 3 x plus 0 point 0 8
D
0 point 1 7 x minus 1 point 5 8

Explanation

Subtract g(x) from f(x): (0.5x + 0.75) − (0.33x − 0.83). Distribute the subtraction, then combine like terms: (0.5 − 0.33)x + (0.75 + 0.83) = 0.17x + 1.58. So the answer is choice A, 0.17x + 1.58.
