Answer: 37.7
Step-by-step explanation:
10 % of 40 = 10/100 ×40=4
When dropped by 10% then amount on Monday = 40-4=36
On tuesday price dropped = 36 - 10 = 26
Increased by 45% on friday : 45/100 × 26 + 26 =
37.7
Number 1. is 1/5 but in decimal form it’s 0.2
you take 2 points on the graph
(3,300) and (6,200)
and then you do <u>y2 -y1</u>
x2-x1
you plug in the values
<u>200-300</u>
6-3 =
every 3 years the resale of a refrigerator decreases by 100 dollars.
its basically the rate that the price goes down for resale value of a refrigerator
F(3)=-4(3)^2+4(3)-4
= -4(9)+12-4
= -36+12-4
F(3)= -28
