Amachine produces
440

bolts in
48

minutes. at the same rate, how many bolts would be produced in
30

minutes?

First, you need to find the average rate of change (the number of bolts produced per minute). To do this you divide 440 by 48, which equals approximately 9.16; therefore, the machine produces approximately 9.16 bolts per minute. To find out how many bolts would be produced in 30 minutes, multiply 9.16 by 30, which is 274.8. Round this number and you get 275 as your final answer. I hope I helped :)

275 bolts would be produced in 30 minutes.
