document.write( "Question 1140055: Profit made by a company when 60 units are sold is R1600. When 150 units are sold profit increases to R5,200. Assume that profit function is linear and of the form - P(u)= a + b(u) where P is profit in Rands and 'u 'is the number of units sold. Determine 1. the Values of a and b. 2. The breakeven level and 3 how many units will yield R12,000 profit?\r

You can put this solution on YOUR website!
The description gives two points, (u, P).
\n" ); document.write( "The points are (60, 1600) and (150, 5200).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Why the dash character in front of the P(u) ? The question describes the need for just finding the linear function. Just use P(u).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"P-1600=%28%285200-1600%29%2F%28150-60%29%29%28u-60%29\"$ , using the point-slope form;\r
