You simply put 40 over a hundred and 55 over n (which is the number were trying to find) so you do cross multiplication. 55 times a hundred and after you get the answer. You divide it by 40 and should get 137.5.
Answer:
<h2>
$30.24!</h2>
Step-by-step explanation:
Find the discounted price by setting up an equation
40-.3(40) AKA 30% of the original price is being taken off of the original price
Evaluate
40-12
$28 = discounted price
Sales tax is based on the reduced/discounted price* remember this
OF= multiplication (in this scenario)
.08x28
$2.24= sales tax
Add tax with discounted price
28+2.24=
<h2>

Answer:
There were 333 seniors in 1990
153 seniors had jobs in 2010.
Step-by-step explanation:
Let the number of high school seniors in 1990 = x
75% of x had jobs in 1990
In 2010 there were 50 more seniors. That is, the number of seniors is x+50.
40% of (x+50) had jobs in 2010.
Total number of jobs in both years = 403.
\[0.75 * x + 0.4 * (x + 50) = 403\]
\[0.75 * x + 0.4 * x + 20 = 403\]
=> \[1.15 * x = 403 - 20\]
=> \[1.15 * x = 383\]
=> \[x = 383/1.15\]
=> \[x = 333\]
Number of seniors having job in 2010 = 0.4 * (333 + 50) = 0.4 * 383 = 153.2 = 153(approx)
