Answer:
D is the correct option.
Step-by-step explanation:
The height went from 25 to 10 cm ( = 15 cm) in 60 minutes . In 20 minutes it will be reduced by 5 cm so the original height was 30 cm ( at time 0).
Looks like option D :
y-25=-.25(x-20)
At x = 0 minutes, y = 30 so:
30 - 25 = 5
-.25(0 - 20) = 5 so that fits.
At time = 20 minutes
25 - 25 = 0
-.25(20 - 20) = 0 That fits
At time 80 minutes:
10 - 25 = -15
-.25(80 - 20) = -.25 * 60 = -15 That fits.
Answer:
157.8
Step-by-step explanation:
so since its on a 80% discount we want to see how much 80% is on $790 which was its initial price. To find out the percentage of $790 we need to multiply $790 by 0.80 which will equal to 631.2.
the answer is 157.8
you have to subtract 790 with 631.2
