Star makes skirts as a hobby. It costs her $34 to make one skirt. Her fixed costs are $275. If she can sell her skirts for $45,

ludmilkaskok [199]

The answer is A. 25
first you subtract 45-34 to find out how much money she makes on one skirt which is $11
then you divide 275÷11 to find out how many she needs to make to break even.
275÷11=25

Decompose 8/12 in two ways with: <br> x/2 + x/2 = 8/12

LUCKY_DIMON [66]

$\frac{x}{2} + \frac{x}{2} = \frac{8}{12} \\\frac{2x}{2} = \frac{2}{3} \\x = \frac{2}{3}$
or
$\frac{x}{2} + \frac{x}{2} = \frac{8}{12} \\\frac{x}{2} + \frac{x}{2} = \frac{2}{3} \\\frac{\frac{2}{3}}{2} + \frac{\frac{2}{3}}{2} = \frac{2}{3} \\\frac{1}{3} + \frac{1}{3} = \frac{2}{3} \\\frac{2}{3} = \frac{2}{3}$
