Nina is selling three types of energy bars at a market stall. She bought 80 Enerbars at 30p per bar and 150 Grainbars at 40p per bar from her normal supplier.

She was also given 40 Amazebars as a promotion from a new supplier.

Nina sells the bars for ÂŁ2.40 and manages to sell all the Enerbars and Grainbars but only some Amazebars.

She makes a profit of ÂŁ520.80.

How many Amazebars did she sell?

doing this for points sorry

Step-by-step explanation:

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
