Maslowich

The clearance price of hat is $17.28

Step-by-step explanation:

Price paid by store = $20

Increment = 60% of price paid

Increment = $\frac{60}{100}*20 = \frac{1200}{100}$

Increment = $12

Increased price = 20+12 = $32

Sale = 10%

Discount amount = 10% of increased price

Discount amount = $\frac{10}{100}*32=\frac{320}{100}$

Discount amount = $3.2

Sale price = 32 - 3.2 = $28.8

Clearance sale = 40%

Discount of clearance sale = 40% of sale price

Discount = $\frac{40}{100}*28.8=\frac{1152}{100}$

Discount = $11.52

Clearance price = sale price - Discount of clearance sale

Clearance price = 28.8 - 11.52 = $17.28

The clearance price of hat is $17.28

almond37 [142]

Answer:

The 7.14% of her income is the income tax .

Step-by-step explanation:

Formula

$Percentage = \frac{Part\ value\times 100}{Total\ value}$

As given

A house painter has an annual income of $35,000 and paid $2,500 in income tax.

Here

Part value = $2500

Total value = $35000

Put in the formula

$Percentage = \frac{2500\times 100}{35000}$

$Percentage = \frac{250000}{35000}$

$Percentage = 7.14\ (Approx)$

Therefore the 7.14% of her income is the income tax .
