Let x be the original cost for the sofa.
X x (1 + 0.07) =3210
X = 3000
Now we know the cost for the sofa.
Let p be the profit percent.
3000 x (1 + p) = 3360
P = 0.12
So the percentage profit is 12%
45 plus 67 gives you a number
To solve:
(x-10)(x-10)
Answer: x^2-20x+100
Answer:
z=-13/7
Step-by-step explanation:
1. Add 3z(7z+5=-8)
2. Subtract 5(7z=-13)
3. Divide 7(z=-13/7)
He had $12.50 left because you do
1.25 + 5= 6.25 and because he spent half earlier you would multiply by two to get 12.5
