Answer:

(2a - $\frac{y}{4}$ )(2a + $\frac{y}{4}$ )

Step-by-step explanation:

4a² - $\frac{y^2}{16}$ ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

4a² - $\frac{y^2}{16}$

= (2a)² - ( $\frac{y}{4}$ )²

= (2a - $\frac{y}{4}$ )(2a + $\frac{y}{4}$ )

3.803% Profit

Step-by-step explanation:

Sale: 120*1.1=132 and 52*.9=46.8

Cost: 120 and 52

Profit equation:

$\frac{Net sales-COGS}{Net Sales} =Profit$

$\frac{(132+46.8)-(120+52)}{(132+46.8)}$

Simplify:

$\frac{6.8}{178.8} =.03803$ or 3.803% Profit
