Answer:
Pip gets £12
David gets £24
Bridget gets £24
Step-by-step explanation:
The ratio 1 : 2 : 2 is Pip : David : Bridget
Add all the numbers in the ratio together.
2+2+1=5.
Divide 60 by 5.
60÷5=12

(9×13) - (5×2) - (3×6)
117 - 10 - 18
= 89 ft²
If you're looking for its length, it is 27 ft. If you're looking for its area, it is 189 ft squared.
The Profit = Revenue - CostP ( x ) = ( 40 x - 0.5 x² ) - ( 5 x + 15 ) = = 40 x - 0.5 x² - 5 x - 15 = - 0.5 x² + 35 x - 15The maximum profit is when: P`( x ) = 0P ` ( x ) = ( - 0.5 x² + 35 x - 15 ) ` = - x + 35- x + 35 = 0x = 35 ( the number of units )P max = - 0.5 · 35² + 35 · 35 - 15 = - 612.5 + 1225 - 15 = 597.5Answer: The maximum profit is 597.5 and the number of units is 35.
