Let the cost of the hair dryer equal x.
The net cost plus a 40% markup equals 42, set up an equation and solve forex.
1.4x = 42
Divide both sides by 1.4
X = 42 / 1.4
X = 30
The net cost was £30
Answer:
-3x+6
Step-by-step explanation:
Again, you multiply -3 times x and you get -3x, then you multiply -3 times -6 and since you are multiplying two negative numbers the result becomes positive so you get +6. Result = -3x+6
The percent error is 34.28 %.
Hope this helps! Be safe out there.
Yes because if you take 4:3 it equals out to be 2:1.5
x is equal to 0 because 6 is already equal to 6
so there shouldnt be another number unless its 0
0+6=6
