A watch cost 75.99. If the sales tax rate is 6.25 percent, what is the amount of sales tax. Plus, please show your work.

rusak2 [61]

So the watch costs 75.99 including sales tax.

The sales tax is 6.25% of the value of the watch.

100% of the value of the watch is n.

100% + 6.25% of the value of the watch is 106.25/100 * n = 75.99

Let's calculate the sales tax...

$\frac { 106.25 }{ 100 } \cdot n=75.99\\ \\ 106.25\cdot n=7,599\\ \\ n=\frac { 7,599 }{ 106.25 }$

$\\ \\ =71.52\\ \\ Sales\quad Tax\quad is\quad Therefore:\\ \\ 75.99\quad -\quad 71.52\quad =\quad 4.47$

Subtract: (4x3 + 9xy + 8y) – (3x3 + 5xy – 8y)

Nikitich [7]

(4x³ + 9xy + 8y) - (3x³ + 5xy - 8y) =

= 4x³ + 9xy + 8y - 3x³ - 5xy + 8y =

= 4x³ - 3x³ + 9xy - 5xy + 8y + 8y =

= x³ + 4xy + 16y ← the end answer
