Question

Find the net decimal equivalent for a special at a nail salon if the salon is offering aseries of four discounts: 35%, 20%, 15%, and 10%.Hint: NDE =1- Discount as a decimal)= (1-Discount as a decimal > (1-Discount as a decimal)x (1- Discount as a decimal)0.3978C0.60220.001050.99895

Answer 1

Given:

Discount 1, d1=35%

Discount 2, d2=20%.

Discount 3, d3=15%.

Discount 4, d4=10%.

The net decimal equaivalent can be calculated as,

`\text{NDE}=(1-(d_1)/(100))*(1-(d_2)/(100))*(1-(d_3)/(100))*(1-(d_4)/(100))`
`\begin{gathered} \text{NDE}=(1-\frac{35_{}}{100})*(1-\frac{20_{}}{100})*(1-\frac{15_{}}{100})*(1-\frac{10_{}}{100}) \\ =(1-0.35)*(1-0.2)*(1-0.15)*(1-.1) \\ =0.65*0.8*0.85*0.9 \\ =0.3978 \end{gathered}`

Therefore, the net decimal equaivalent of discount is 0.3978.
