John has a fruit shop. He buys apples at $1.25 from the wholesale market and sells them at $1.35 at his store. i)By what percentage has the Apple's price been increased. ii) If he sells 30 apples that day, how much money will he earn and How many apples can he buy for the next day after saving 10% of his earnings.

i)We first have to calculate the difference between the cost and selling price: $1.35 - $1.25 = $0.10. The difference divided by the original gives us the answer. So 0.10/1.25 x by 100 = 8%. ii) 30 x $1.35 = $40.5 (his total earning that day from selling apples) 10% of total earning = 0.10 x 40.5 = $4.05 to find out how much money he can use for buying apples the next day, we must subtract the 10% from the total earnings. $40.5 - $4.05 = $36.45 to find out the number of apples he can buy, divide $36.45 by the cost price of apples($1.25) = 29.16 apples, to the nearest round number, 29 apples.
