Answer:
Based on the results <u>200</u> of the 340 students can be expected to prefer cheese pizza.
Step-by-step explanation:
Given:
Cheese pizza was preferred by 40 students.
Pepperoni pizza was preferred by 28 students.
Now, based on the results how many students of the 340 can be expected to prefer cheese pizza.
Number of students preferred cheese pizza = 40.
Number of students preferred pepperoni pizza = 28.
Total number of students = 40+28 = 68.
As, 40 out of 68 preferred cheese pizza.
<em>To get the number of the students out of 340 students who preferred cheese pizza based on the results</em>.
Let the students be who preferred cheese pizza.
So, we set proportion:
40:68 = : 340.
Now, solving by using cross multiplication method:
<em>By cross multiplying we get:</em>
<em>Dividing both sides by 68 we get:</em>
Therefore, based on the results 200 of the 340 students can be expected to prefer cheese pizza.

Step-by-step explanation:
Ellen's pay is:
Fixed Weekly Salary (that is $330) + 12% commission on Sales
We already know her fixed salary part. Let's figure out her last week's commission and add it to her fixed salary to find her total pay.
12% is 12/100 = 0.12
To find 12% of 1200, we multiply 1200 with 0.12. We get:
So her commissions for last week is $144.
Total Pay Last Week = 330 + 144 = $474
