a small business woman has realised that one of her products, if the price per unit is ghc 20 she can sell 300 units a day. On the other hand, if thr price per unit is reduced to ghc13 ,she can sell 440 units a day .from the accounting records, her accountant has estimated the fixed cost of production as ghc 2000 with a variable cost per unit of ghc 10 .find an expression relating price and outpuy assuming it is linear . state the total cost function assuming it is linear . advice the business woman on the level of production at which she will break even. state the break even values

she drove 134 miles

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

one fourth of 9% = 2.25%

gavin is correct in saying : the equivalent quarterly interest rate would be

2.25%.
