Question

Josephine noticed that out of 10 e-mails she received, 7 were advertisements. What can she predict about the number of advertisements she will receive in the next 100 e-mails? A.She will receive 7 advertisements. B.She will receive 10 advertisements. C.She will receive 70 advertisements. D.She will receive 90 advertisements.

Answer 1

Answer:

C. She will receive 70 ads

Step-by-step explanation:

Let the no. of ads she will receive on 100 emails be 'x'

So, 7/10 = x/100

    7 x 100 = 10x

    700 = 10x

    700/10 = x

    70 = x

Therefore x= 70
