The snowboard Hannah wanted originally cost $109.It had been marked down 10% and then another 12%. A tax of 6% was added to the

lara [203]

Take 10% of the snowboard price.

10% = 0.1

109 * 0.1 = $10.90 (10% discount)

109 - 10.9 = $98.10 (Price with discount).

Take 12% of the new snowboard price.

12% = 0.12

98.1 * 0.12 = 11.772 (Round to 11.77)

98.10 - 11.77 = $86.33 (Final discounted price)

Take 6% tax on the new snowboard price.

6% = 0.06

86.33 * 0.06 = 5.1798 (Round to 5.18)

86.33 + 5.18 = $91.51

A baby is weighed on a defective scale. He weighed 28 pounds according to the scale. He weighs 25 pounds on an effective scale.

Anettt [7]

Answer:

Step-by-step explanation:

Step one:

given

expected weight= 28pounds

Actual weight= 25 pound

Required:

percent error

$\delta = \left| \frac{v_A - v_E}{v_E} \right| \cdot 100\%$

δ= percent error

vA =actual value observed

vE =expected value

δ=25-28/28*100

δ=-3/28*100

δ=0.107*100

δ=10.7%

The percent error is 10.7%
