Help, i know the answer but i don’t know how to do the work

Diano4ka-milaya [45]

Answer:

C

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplifying each radical before combining them.

$\sqrt{45t}$

= $\sqrt{9(5t)}$

= $\sqrt{9}$ × $\sqrt{5t}$ = 3 $\sqrt{5t}$

-----------------------------------------------------------------------------

$\sqrt{125t}$

= $\sqrt{25(5t)}$

= $\sqrt{25}$ × $\sqrt{5t}$ = 5 $\sqrt{5t}$

---------------------------------------------------------------------------

Hence

2(3 $\sqrt{5t}$ ) - 3(5 $\sqrt{5t}$

= 6 $\sqrt{5t}$ - 15 $\sqrt{5t}$

= - 9 $\sqrt{5t}$ → C

Answer:

$14.49

Step-by-step explanation:

Since the question asked you how much you spent on the meal including the 5% tax and the 15% tip after the tax, it's basically asking you to calculate the percentage of the meal and subtracting it by the amount.
