a) 170.00 =8n -30
200= 8n
n = 200/8 = 25 items
b) since the expenses increased the profits would decrease
profit = 8(25)-40 = 200-40 = 160
170-160 = 10.00
profit decreased by $10.00
I'm assuming the 59% achievement means, markup, so hmmmm well, if the bananas cost him $0.24 or 24cents per pound, so a markup of 59% is just 59% of 0.24 then.
whatever% of anything is just (whatever/100) * anything.
therefore, 59% of 0.24 is just (59/100) * 0.24, or 0.1416.
so, if we add 0.1416 to the 0.24, the selling price will be 0.3816, or just 38cents per pound of bananas.
