Answer:
Part a)
Part b) The cost to take classes every weekend (Saturday and Sunday) during the month of January is $140
Step-by-step explanation:
Part a)
Let
x ----> the number of classes
y ----> the total cost
we know that
The equation of the line in slope intercept form is equal to
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
In this problem
The slope is equal to
The y-intercept is ---> annual fee
substitute
Part b) Use the equation from above and find out how much it would cost to take classes every weekend (Saturday and Sunday) during the month of January
we know that
During the month of January 2020 we have 8 classes (4 Saturday and 4 Sunday)
so
For x=8
substitute in the linear equation
therefore
The cost to take classes every weekend (Saturday and Sunday) during the month of January is $140
The answer is 62.5 minutes because...
40 question would be 50 minutes and then you still have 10 more so divide 25 by 2 to get 12.5
Finally add everything together (25+25+12.5=62.5)
Answer: The answer on 39 is c and theanswer on 40 is J
Step-by-step explanation:
Add the sides together and u get 19!
I used mental math and it took a long time, but I got the answer of 2,499.
