Answer:
Part A
12 months a year means
%74.5 x 12 = $894
Part B
4 weeks in a month means
$74.5 ÷ 4 = $18.625
But rounded to the nearest penny. . .
$18.62
because in the thousandths place was a 5 and you round up when there is a 5 or above
Part C
We will go with 31 days in a month, but I will also do 30 for you
$74.5 ÷ 30 = $2.48333
But rounded to the nearest penny. . .
$2.48
because you round down when there is anything less than a 4
$74.5 ÷ 31 = $2.40322580645
But rounded to the nearest penny. . .
$2.40
because you round down when there is anything less than a 4
Answer:
x^2 - 9x + 20
Step-by-step explanation:
(x - 4)(x - 5) (have to do the opposite for it to be positive)
FOIL method: X x X = x^2
-5 x X = -5x
-4 x X = -4x
x^2 - 5x - 4x + 20
-5 - 4 = -9 so...
x^2 - 9x +20 is the answer
A number that is greater than 714,587 is 1,000,000
