Answer: 7.2$
hope it helps :)
step-by-step explanation:
Cost of each box = 3$
Cost of 3 boxes without 20% coupon = 9$
With 20% off Coupon = 9 by 100 multiplied by 20
(the zero's cut with each other leaving)
= 9 by 10 multiplied by 2
(9 multiplied by 2 = 18)
= 18 by 10
(18 divided by 10 = 1.8)
= the 20% of 9$ is equal to 1.8
when subtracted with the total cost leaves 7.2$
Answer:
- Student cannot determine proportionality because there is no y-intercept.
- Table and graph do not match
(Student does not realize they are based on two different people)
- Student computes x/y and not y/x (Ex. 3/27 or 2/18)
Step-by-step explanation:
-May not be able to determine Unit rate because (1, r) does not exist on the table.
-May answer “18” because it is the first point on the table.
-Unable to determine relationship between x and y values
Add 2 to both sides
11+2 = 13
m=13
X=0 Is the equation for the graph listed above.
B.
Answer: $24, $34, $45.9, $50, $50.4, $54.4, $78.4
Step-by-step explanation: I'm not seeing the tree on this thing, so this would be a wild guess.
