It Is O. 8
Step-by-step explanation:
Because you are suppose to round the number to the one in front of the other number
500 at 40 each = £20000
To make a profit he needs to make more than £20000
20 broke so he sold 500-20 = 480 at 45 each.
480 x 45 = 21600
Profit = 21600 -20000 = 1600
His profit was £1,600
