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)
