Step-by-step explanation:
Find the vanilla first by dividing 420 by 7 and multiplying the quotient by 2 to get 120.
Then find the banana using the equation 35/100 = x/420, cross multiply to get 147.
Add 120 and 147 to get 267.
Subtract 267 from 420 to get 153.
Divide 153 by 9 to get 17.

<h3>
97, 485 and 197</h3>
Step-by-step explanation:
x - the first number
One number is 5 times a first number:
5x - "one" number (the second number)
A third number is 100 more than the first number:
x + 100 - the third number
x + 5x + x+100 - the sum of the three numbers
x + 5x + x+100 = 779
-100 -100
7x = 679
÷7 ÷7
x = 97
5x = 5•97 = 485
x+100 = 97 + 100 = 197
Check:
97 + 485 + 197 = 779
Answer:
<h2>
The manager's claim is likely to be true.</h2>
Step-by-step explanation:
We are given that the factory produces 42,000 computer monitors per day
And the claim is of this amount produces fewer than 660 are defective.
a random sample shows that of 240 monitors 2 are defective
to verify the factory managers claim we need to know how many 240s are there in 42000
=42000/240= 175
Since each 240 will give 2 defective monitors
175 will give= 175*2= 350
350 is less than 660 hence the managers claim is correct
