NEED HELP!!!

AnnyKZ [126]

Answer:

see explanation

Step-by-step explanation:

(1)

$\frac{6}{2}$ = $\frac{4}{p}$ ( cross- multiply )

6p = 8 ( divide both sides by 6 )

p = $\frac{8}{6}$ = $\frac{4}{3}$

(2)

$\frac{n}{4}$ = $\frac{8}{7}$ ( cross- multiply )

7n = 32 ( divide both sides by 7 )

n = $\frac{32}{7}$

(3)

$\frac{5}{3}$ = $\frac{x}{4}$ ( cross- multiply )

3x = 20 ( divide both sides by 3 )

x = $\frac{20}{3}$

you go to a restaurant with four other people the total food is $43.85 you need to add 5% for tax and 15% for tip if you decide

Bingel [31]

Multiply $43.85 by .05, take that add to original price and get $46.04. Next take $46.04 multiply that by .15, you will get $6.90. Then add it to $46.06 and get $52.94, divide by 4 and you will pay $13.24.
