Answer:
$20.15
Step-by-step explanation:
Given data
Original cost = $9.57
Markup= 95%
Let us find the new cost of the basket
=95/100*9.57
=0.95*9.57
=$9.0915
Hence the cost of the basket is
= 9.57+9.0915
=18.66
Also, the sales tax is 8%
=8/100*18.66
=0.08*18.66
=1.4928
Therefore, the total amount to be paid is
=18.66+1.4928
=$20.15
But it is not a complete question.
In 1st fig
A=5×x(let)
9=5×x
in 2nd fig
A=10×2x(5 is doubled so ×also doubled)
A=10×2×9÷5
A=36

<u>Step 1: Define</u>
3|x + y|² - (xy)²
x = 3
y = -5
<u>Step 2: Evaluate</u>
- Substitute: 3|3 - 5|² - (3(-5))²
- Multiply: 3|-2|² - (-15)²
- Exponents: 3|-2|² - 225
- Absolute Value: 3(2)² - 225
- Exponents: 3(4) - 225
- Multiply: 12 - 225
- Subtract: -213
