Y/(X•grams), find the total cost of the gold, then use y to divide the whole thing.
Hi!
We will solve this using ratios, like this:
1 shelf holds 45 pounds
x shelves hold 270 pounds
______________________
x = (270*1)/45
x = 270/45
x = 6
6 shelves will be needed to hold 270 pounds of boxes.
Hope this helps!
4 first rows have 6
5th row has 4
there are 28 computers
In finding this value you average lower and upper bound
(0.6+0.82)/2 = 0.71
=0.71 estimated
margin of error = distance from estimate point lower/ upper bound
This interval will be twice margin error
(0.82-0.6)/2 = 0.11
How far is 0.82 from 0.71 ??
=0.11=11%
