Let's say, the total sales is "x"... .so hmm on Plan A, he gets 350 plus 7% of "x", well, 7% is just (7/100) * x or 0.07x
now, on Plan B, he gets 436 plus 5% of "x", 5% of "x" is (5/100) * x, or 0.05x
he's better off with A, only if A is greater than B, namely,
A > B
and surely you know how much that is.
Answer:
-59
Step-by-step explanation:
f(x) = -2x - 7 and g(x) = -4x + 6.
f(g(x)) =
Replace x in the function f(x) with g(x)
= -2(-4x+6) -7
= 8x -12 -7
= 8x - 19
Let x = -5
f(g(-5) = 8(-5) -19
= -40 -19
= -59
Answer:
Option 'b' i.e. -11/20 is the correct option.
Thus,

Step-by-step explanation:
Given the expression

Determining the difference of the fractions

The Least Common Multiplier of 5, 4 is 20. Thus, adjust the fractions based on the L.C.M.

Apply the fraction rule: 

Add the number: 4-15 = -11

Apply the fraction rule: 

Please check the attached figure, where the pointing-down arrow is representing the correct answer which is -11/20.
Therefore, option 'b' i.e. -11/20 is the correct option.
Thus,
