Answer:
y=3x+5
Step-by-step explanation:
Since the equation will be parallel, the slope will still be 3.
y=3x+b
Enter the point (1,8) into the equation.
8=3(1)+b
8=3+b
b=5
y=3x+5
All you have to do is find 40% or .4 of 90.
90 x .4 = 36
36$ is the mark up, so the total price would be 126$.
Answer:
29. A 30. $7.50 31. 1(2) 1(3) 3(4) 1(5) 1(6) 1(7)
Step-by-step explanation:
29.
multiply $2500 by the percentage (ie. 24%) that is how to get the amount.
30.
if 4 boxes equal $5.00 and Jeniffer has 6 then 4 of her 6 equal 5.00 and half of five is 2.50 which mean the 2 remaining would be added and would equal $7.50
31.
you add 1 dot to the top of the number for every time that one number shows up (example: if you have 3 2's, then you add 3 dots to the top of the number 2)
