An antique dealer has 24 clock radios to sell at 12 a 12 hour long antique Radio sale use the graph to complete the table why is the sign of a number that is multiplied by hours H negative
Answers
Answer:
R = -H + 24
Step-by-step explanation:
An antique dealer has 24 clock radios to sell 12 at a 12 hour long antique Radio sale
12 radios are sold in 12 Hour
Table
Hours Radio Available Remaining
0 24
2 22
4 20
6 18
8 16
10 14
12 12
Line of equation R = mH + c
R = Radios Available / Remaining to be sold
H = Hours of Sale passed
m = slope of line
c = constant
H = 0 , R = 24
24 = 0 + c
=> c = 24
R = mH + 24
for H =2 R = 22
22 = 2m + 24
=> m = -1
R = -H + 24
As every passing hour he will be able to sell a radio so number of radios available will keep decreasing so there is a sign of - multiplied by H
24 is the radio available at beginning of sale.
if we plot a graph for Radio sold against hours
then equation would be
R = H ( c = 0 as no radio sold at beginning of sale)
