Question

The acme class ring company designs and sells two types of rings: the VIP and the SST. The company can produce up to 140 rooms each day, using up to 350 total many hours of labor. It takes 7 man- hours to make one VIP ring and 5 man hours to make one SST ring. Let x represent VIP and y represent SST.

A.) x+y≤140, 7x+5y≤350, x≥0, y≥0

B.) 0≤x≤140, 0≤y0≤140, 7x+5y≤350

C.) x+y≤140, 5x+7y≤350, x≥0, y≥0

D.) 0≤x≤140, 0≤y0≤140, 5x+7y≤350

Answer 1

Hi Britney, the answer is A. 

 

The total number of rings is less than or equal to 140:

 

x + y ≤ 140

 

The total number of man hours is less than or equal to 350:

 

7x + 5y ≤ 350

 

Both x and y have to be greater than or equal to 0:

 

x ≥ 0

 

y ≥ 0
