Answer:

40,640,000

Step-by-step explanation:

The way I solved this equation was by dividing 320,000,000 by 1,000 (to make smaller numbers). Then, I got 320,000. From here, I was able to multiply 320,000 by 127 (the number found in this specific study group) to get 40,640,000. Or, you could just multiply 320,000,000 by 0.127 (the decimal equivalent to 127/1000) to get the same answer. Please mark Brainliest if this helped :)

Answer:

40,640,000

Step-by-step explanation:

The sample size is 1000 and 127 wear contacts so

127/1000 = x/320000000

(127 * 320000000)/1000 = x

40,640,000 = x
