Answer:
$89.93
Step-by-step explanation:
Set up an equation:
Variable x = original price
40/100 = 35.97/x
Cross multiply
40 × x = 100 × 35.97
40x = 3597
Divide both sides by 40
x = 89.925
Round to the nearest cent:
5 rounds up so:
89.93
Check your work (use the original number instead of the rounded number to be more exact):
89.925 × 40%
Convert the percentage into a decimal to multiply:
89.925 × 0.40
35.97
Correct!
Answer:
C
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (- 3, 4)
m =
=
= -
→ C
Answer B shows the correct information. If you look at the totals of the tables, B shows that 30 aren't in a band, 20 are in a band, and 25 play an instrument.
25 (units of distance/units of time)
The first two seconds are determined between points (0,50) and (2,100). Given these points, finding the slope between them gives you the average rate of change:
It costs $4.50 per game.
You just divide 18 by 4. If you want to check your answer divide 27 by 6
