Reasoning and answer: Mowing lawns will earn Julie 20 * 20 = 400 dollars. Her earnings, in dollars, from delivering newspapers will be 600 * 40 / 100 = 240 dollars. After walking 24 of her neighbor’s dogs, she will earn 24 * 15 = 360 dollars. She will therefore earn a total of 400 + 240 + 360 = 1000 dollars. Combining earnings from her job with her savings will give Julie 1000 + 1500 = 2500 dollars. Subtracting the cost of the mountain bike from the total will leave Julie with a balance of 2500 - 2345 = 155 dollars.
The answer: 155
