kirza4 [7]

Answer:

747

Step-by-step explanation:

let the 2 numbers be x and y with x > y, then

x - y = 275 ( the difference of the 2 numbers ) and

x - 236 = 275 ( the smaller number y = 236 )

Add 236 to both sides

x = 511

Thus x = 511 and y = 236, thus

x + y = 511 + 236 = 747

\frac{8}{40}*100=20\%

Based on the sample survey, only 20 percent of the members will sign the petition. Since, in the sample, the number of those who will sign is less than 33%, the union should be told that there is no need for the National Labor Relations Board to call for the election.
