maxonik [38]

Answer:

$13.20/hr

Step-by-step explanation:

A 10% wage increase would amount to 0.10($12) = $1.20.  Adding this increase to the starting rate $12/hr results in $13.20/ hr.

A faster way in which to do this is shown below:

Wages after a 10% increase = (1.10)($12/hr) = $13.20/hr

At the farm, Justin picks 3 bushels of fruits. The bushels weigh 8 1/4 pounds, 6 1/2 pounds, and 6 5/8 pounds. What is the avera
blondinia [14]
ANSWER

Average \: Weight =  7 \frac{1}{8}  \: bushels


EXPLANATION

To find the average weight per bushel, we add all the three weight and divide by 3.


Average \: Weight =  \frac{8 \frac{1}{4}  + 6 \frac{1}{2} + 6 \frac{5}{8}  }{3}


We convert all the mixed numbers to improper fraction to obtain,


Average \: Weight =  \frac{ \frac{33}{4}  +  \frac{13}{2} + \frac{53}{8}  }{3}


The least common denominator for the fractions in the numerator is 8.


This implies that,

Average \: Weight =  \frac{ \frac{66 + 52 + 53}{8} }{3}

This simplifies to


Average \: Weight =  \frac{ \frac{171}{8} }{3}


This gives us,

Average \: Weight =   \frac{171}{24}



Average \: Weight =   \frac{57}{8}


Average \: Weight =  7 \frac{1}{8}
