7/6

Step-by-step explanation:

$\frac{ \frac{x}{4} + \frac{x}{3} }{ \frac{x}{2} } = \frac{x( \frac{1}{4} + \frac{1}{3} )}{ x(\frac{1}{2}) } \\ = \frac{ \frac{1}{4} + \frac{1}{3} }{ \frac{1}{2} } \\ = \frac{14}{12} = \frac{7}{6}$

Answer is 36.
First use the negative exponent rule. When a number is put to the negative power it becomes a fraction
4/3^2

Now 3 to the second power is 9
4/1/9 (4 over 1/9)
Now multiply 4 x 9 (dividing by 1/9 is the same as multiplying by 9)

4 x 9= 36

Aleonysh [2.5K]

Answer:

$43.20

Step-by-step explanation:

To find the original purchase price, write a proportion and solve. A proportion is an equation where two ratios are set equal.

If the discount if 15% then you pay 85%.

$\frac{36.72}{y}= \frac{85}{100}$

To solve for y, cross multiply the numerator and denominator of each fraction.

36.72(100) = 85y

3672= 85y

43.2 = y
