Answer:
300
Step-by-step explanation:
Students like Vanilla ice cream = 86
Out of 86 Students like chocolate ice cream too = 48
So, No. of students who like only vanilla=86-48 = 38
There were 12 students who did not like vanilla ice cream but liked chocolate ice cream.
There were 2 students who did not like either vanilla ice cream or chocolate ice
Like Vanilla Did not like vanilla Total
Like Chocolate 48 12 60
Did not like chocolate 38 2 40
Total 86 14 100
No. of students who like chocolate out of 100 = 60
Now we are supposed to find the number of students who would like chocolate ice cream when 500 high school students participate in the survey.
Let x be the number of students out of 500 who like chocolate
So, A.T.Q
Hence the number of students who would like chocolate ice cream when 500 high school students participate in the survey is 300.
Answer:
x + y = 13
98x + 115y = z
Step-by-step explanation:
Let x represent the time spent taking class in Westside community college
Let y represent the time spent taking class in Pinewood community college
Let z represent the combined total amount paid for the class fees.
The total combined time for the two school is given as:
x + y = 13.
For the combined total amount; we multiply the price for each school with the time spent on the school and sum them together.
Westside:
Pinewood:
The combined total amount represented as z is given as:
z = 98x + 115y
