Question
Kelly saved $150. That is 50% of the money she earned this summer. How much did Kelly earn this summer?
Answer:
<h2>
300$</h2>
Step-by-step explanation:
50% = 1/2 = 0.5
150 is the 50% of the money she earned this summer.
Solution
150 * 2 = 300$
Three consecutive odd integers are n, n+2 and n+4
n + n+2 + n+4 = -87
3n + 6 = -87
3n = -87 - 6
3n = -93
n = -93/3
n = -31
n+2 = -31 + 2 = -29
n+4 = -31 + 4 = -27
The numbers are -31, -29 and -27
