Answer:
1.8
Step-by-step explanation:
Mean is when you add all of them together and divide by the amount of data you collected. Mean is considered the average. So, all of them added together would be 14. Divide that by 7. You should get 2 and that is the average.
Let's start by plugging in 1 for y. You get 7-2/6, which is 5/6. The other equation is 3-7/12, which equals -1/3. Now let's try 10. You get 7-2(10)/6, which is -13/6. The other equation is 3(10)-7/12, which is 23/12, and is larger!
1 is a value of y that could work!
Hope this helps!! :)
You can set up a proportion. The quick answer is 600
7.5/900 = 2.5/x
x = 900 * 2.5 / 7.5
x = 900 * (1/3)
x = 300
But that is not the answer. The question is what does she save.
900 - 300 = 600
You could get the answer more directly. She does not eat 5 oz cake, so solve for that.
5/x = 7.5/900 Cross multiply
5 * 900 = 7.5 x
4500 = 7.5x Divide by 7.5
4500/7.5 = x
600 = x
