Answer:
Step-by-step explanation:
A)
This is the 30% discount:
$39.99 x .30 = $11.997; The discount is $11.997
Price of headphones after the discount:
$39.99 - $11.997 = $27.99
Now we need to calculate the 6% sales tax on the discounted price.
$27.99 x .06 = $1.68 (rounded off)
Dalton paid $1.68 in sales tax on the discounted price.
B)
The total price Dalton paid for the headphones will be the discounted price plus the sales tax.
$27.99 + $1.68 = $29.67
Total price Dalton paid: $29.67
Answer:
A - $10
Step-by-step explanation:
The equation f(x) = 0.50x + 10 is in the form
y = mx + c where m is the gradient and c is the intercept.
The price of the entrance fee will be the intercept because that is when x is equal to 0, meaning it will be $10.
Answer:
Population 120 given the survey, sample 90 who answered the survey.
Step-by-step explanation:
The entire amount of employees who even received the surveys at all was 120. Because the total number was 120, 120 is the population.
Only 90 out of 120 surveys were received, so 90 is the sample because it is part of 120.
Hope this helps :)

Answer:
A function is a relation in which each element of the domain, or x-value, is mapped to one element of the range, or y-value.
The question we are asked is if cost is a function of the activity type. This means that cost would be the range and activity type would be the domain.
If this is a function, then each activity type would have only one cost. However, on different days of the week each activity type has different prices; this means there is more than one cost for each activity type, and it is not a function.
