Which business document is usually written in block style with the body text aligned along its left margin? the is usually written in block style with the body text aligned along the left margin.

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30
