Answer:
P= -2x +46
Step-by-step explanation:
the relation between price and demand is
P= mx +b ........................1
when demand is 10 shirts price is $26
when demand is 20 shirts price is $6
firstly put P= 26 and x= 10 in 1
26= 10m + b.......................2
secondly put x= 20 and P= 6 in 1
6= 20m + b ............................3
solving 2 and 3 we get
m = -2
putting this value of m in either of 2 and 3 to get b
b= 46
so the final relation obtained by putting m= -2 and b= 46 in 1 we get
P= -2x +46
