Answer: $81.60
Step-by-step explanation:
When we have an original price OP, and a markup of X% (this is how much increases the price with respect to the original price)
The retail price will be:
RP = OP + (X%/100%)*OP
RP = OP*(1 + X%/100%)
In this case, we have:
Original price = OP = $68
markup = X% = 20%
Replacing these in the above equation, we get:
RP= $68*(1 + 20%/100%) = $68*(1 + 0.20)
RP = $68*(1.20) = $81.60
Then the retail price of this particular item is $81.60
Answer:
Step-by-step explanation:
Replace the variables with the number it is so
5. 3 • 8 - 8 = 16
6. 6 • 1/2 divide by 3 + 9 = 10
7. 8 to the power of 2-12• 1/2 divided by 3 = 62
8. 5 • 3-2 • 3 + 8= 17
9. 824/ 4 = 206
10. 6• 60/ 9 - 22 = 18
11. 16.8/2.4 = 7
12. 9.85 • 4 = 39.5
(“•” mean multiply)

As decimal answers:
x = -6.2749172 ≈-6.3
x = 1.27491722 ≈ 1.3
Step-by-step explanation:
For quadratic equations, you can use the quadratic formula. Rearrange the equation to standard from, which is ax² + bx + c = 0.
x² = –5x + 8
x² + 5x - 8 = 0
State the values for "a", "b" and "c",
a = 1; b = 5; c = -8
(Ignore the Â, it's a formatting error)
Simplify
Two negatives make a positive
Split the equation at the ± for plus and minus:
= 1.27491722 ≈ 1.3
= -6.2749172 ≈ -6.3
Therefore the solutions are 1.3 and -6.3.
