X = 1 hr lessons and y = 1/2 hr lessons
x + y = 35......y = 35 - x
40x + 25y = 1115
40x + 25(35 - x) = 1115
40x + 875 - 25x = 1115
40x - 25x = 1115 - 875
15x = 240
x = 240/15
x = 16 <=== there are 16 one-hr lessons
and 19 half-hr lessons
Answer: Neither, Both Unit Prices are equal.
Step-by-step explanation: In order to find the unit price of an item, you divide the quantity by the price. In this case, the Big Lots would be 5.88/12 which equals 49 cents. The Walmart Batteries are 8.82/18 which is also 49 cents. So both batteries are the same price, you should buy the better quality battery in this situation.
Your reasoning is correct, but you made a mistake with your long division.
1248/98 = 12 remainder 72
