Answer:
$935.39
Step-by-step explanation:
Annual salary is 38,000 per year which has 52 weeks so the weekly pay is 38000:52
The amount he earns in 4 weeks is 4(38000):52
The fee is 0.32 times 4(38000)/52 = 935.39
Answer:
25452
Step-by-step explanation:
each term goes up by 5 so the formula is 2+5(n-1) where n is the term number
so the equation is ∑n=1 101 (2+5(n-1))
∑n=1 101 (5n-3) = 25452
Option D is the correct answer
I cannot see Zoe's work to explain the error, but the correct method of solving is listed:
x is the number of 30-second ads
y is the number of 60-second ads
x+y=12(60)=720 would be the first equation; this is because while the ads together make 12 minutes, the ad times are in seconds. This means we must multiply 12 by 60.
y=2x is the second equation
Our system is then
x+y=720
y=2x
We will use substitution to solve this. Plug 2x in place of y in the first equation:
x+2x = 720
Combine like terms:
3x = 720
Divide both sides by 3:
3x/3 = 720/3
x = 240
Substitute this value in for x in the second equation:
y=2(240)
y=480
