in short, 25% is just 1/4 of anything, we know she's sold 25% which is $600, so her daily goal must be 1/4 + 1/4 + 1/4 + 1/4, or namely 600 + 600 + 600 + 600 = 2400.
9(p - 4) = -18
Simplify our equation by multiplying the parenthesis out.
(9 × p) + (9 × -4) = -18
Simplify.
9p + (-36) = -18
Get rid of parenthesis.
9p - 36 = -18
Now, since we're trying to isolate "p," we need to add 36 to both sides.
9p - 36 + 36 = -18 + 36
Simplify.
9p = 18
Divide both sides by 9.
9p ÷ 9 = 18 ÷ 9
Simplify.
p = 2

Assuming n starts from 1.
∑
; n = 1 to 3
45% * x=72
45/100 *x=72
45x/100=72
45x=7200 /:45
x=160
<em /><em><u>⇒72 is 45% of 160.</u></em>
