David and Patti each decomposed 138. David wrote 1 + 1/8 + 3/8. Patti wrote 4/8+2/8+5/8.

BaLLatris [955]

Answer:

Both are wrong.

Step-by-step explanation:

We have that:

Both decomposed the fraction $\frac{13}{8}$ into a sum of fractions. Whoever's decomposition sum has a value of $\frac{13}{8}$ is correct.

David:

$1 + \frac{1}{8} + \frac{3}{8} = \frac{8}{8} + \frac{1}{8} + \frac{3}{8} = \frac{8+1+3}{8} = \frac{12}{8}$

$\frac{12}{8} \neq \frac{13}{8}$ , which means that David is wrong.

Patti

$\frac{4}{8} + \frac{2}{8} + \frac{5}{8} = \frac{4+2+5}{8} = \frac{11}{8}$

$\frac{11}{8} \neq \frac{13}{8}$ , which means that Patti is wrong.

So the answer is that both are wrong.

The current cost of gourmet coffee Is $14 per pound At the corner market the cost has increased 10% Per year over the past few y

KonstantinChe [14]

Answer:

$11.57

Step-by-step explanation:

Let's call the price of the coffee two years ago by X.

The price increased 10% per year (that is, the price is multiplied by 1+0.1=1.1) over two years, so the current price is:

X * 1.10 * 1.10 = X * 1.21

If the current price is $14, we have that:

X * 1.21 = 14

X = 14/1.21 = 11.57

The price of the coffee two years ago was $11.57
