Answer:

for #1: the new price is $37.80 and the amount discounted was $7.20

Step-by-step explanation:

convert 16% to a decimal and multiply to find how much discounted then subtract that from the initial value

0.16*45= 7.20

45-7.20= 37.80

did u need the others too?

So,

$\frac{x}{5} -7 =2q$

Multiply both sides by 5.
$x -35 =10q$

Add 35 to both sides.
$x =10q+35$

$(x-4)(x-2i)(x+2i)=\\
(x-4)(x^2+4)=\\
x^3+4x-4x^2-16=\\
x^3-4x^2+4x-16$
