Find the quotient and the remainder: (x^2+3x-4)/(x-1)
skelet666 [1.2K]
Evaluate this...
\frac{x^2+3x-4}{x-1}
the x at the bottom cancels out one of the xs at the top so it will be
\frac{x^2+2x-4}{-1}
Now the one cancels out one of the 1s in the -4 so
{x^2+2x-3}

Hope this helps :)

bagirrra123 [75]

Answer:

a) $1.40   b) $9.35   c) $57.50

Step-by-step explanation:

a) The tax on the burger will be 3% of the cost of the burger.

This means 0.03 of 46.75 (0.03 x 46.75) = $1.40 tax

b) 20% of pre tax bill as tip would be:

0.20 of 46.75 (0.20 x 46.75) = $9.35 tip

c)Total cost of dinner including tax and tip would be:

Original Cost + Tax + Tip

= 46.75 + 1.40 + 9.35

= $57.50 total
