Hello!
To calculate the sale price of the coat, we can simply multiply 150 by .40, then subtract the product from 150.
150 × .40 = 60
150 - 60 = 90
The sale price of the coat is $90.
7P3= 7!/(7-3)!
= 7!/4!
= 7*6*5
= 210
C.210
From my knowledge, I think it is 9
{ 0 x ≤ 5
f(x) = { 5 6 ≤ x < 18
{ 8 x ≥ 18
The brackets should be one big bracket.
I don’t know for sure but the length is 40 and the width is 10.
