The total amount is "x", so, if 22.8 is 58%, "x" is the 100%,
Answer:
a = 1 and b = - 10
Step-by-step explanation:
Expand the right side of the identity
x(ax² - 3x + b) - 3(ax² - 3x + b)
= ax³ - 3x² + bx - 3ax² + 9x - 3b
= ax³ - x²(3 + 3a) + x(b + 9) - 3b
Equate the coefficients of like terms on both sides of the identity
x³ terms → ax³ with x³ ⇒ a = 1
x terms → - x with (b + 9)x ⇒ b + 9 = - 1 ⇒ b = - 10
Answer:
Sales tax is 8.33 % of new total
Step-by-step explanation:
Let
Your bill =1000
New total 60%=1000*60/100=600
5% sale tax on whole bill price =1000*5/100=50
To deduct 5% sale tax in 60% of new total the % are=50/600=0.0833*100=8.33%
So,
Sale tax is 8.33% of new total 60%.
