Well, is just a matter of addition, namely 4  1/2 + 6  2/3 + 9  1/4.

now, let's change all mixed fractions firstly, to "improper" fractions, and proceed from there,

\bf \stackrel{mixed}{4\frac{1}{2}}\implies \cfrac{4\cdot 2+}{1}\implies \stackrel{improper}{\cfrac{9}{2}}
\\\\\\
\stackrel{mixed}{6\frac{2}{3}}\implies \cfrac{6\cdot 3+2}{3}\implies \stackrel{improper}{\cfrac{20}{3}}
\\\\\\
\stackrel{mixed}{9\frac{1}{4}}\implies \cfrac{9\cdot 4+1}{}\implies \stackrel{improper}{\cfrac{37}{4}}\\\\
-------------------------------\\\\

\bf \cfrac{9}{2}+\cfrac{20}{3}+\cfrac{37}{4}\impliedby \textit{our LCD is clearly \underline{12}}\implies \cfrac{(6)9+(4)20+(3)37}{12}
\\\\\\
\cfrac{245}{12}\implies 20\frac{5}{12}

Ray earns $15 an hour for up to 40 hours a week. If he works more than 40 hours a week, he is paid time and a half. That means R
nekit [7.7K]

Answer:

$7.50

Step-by-step explanation:

His normal pay is $15/h

Find the OT pay:

OT pay is 150% of his normal pay. Convert 150% to a decimal by dividing by 100 to find the rate in decimal form.

150%/100 = 1.5

Multiply his normal pay by the rate in decimal form.

$15 X 1.5 = $22.5

His OT pay is $22.5/h.

Additional money

= (OT pay) - (Normal pay)

= $22.5 - $15

= $7.5

We always use two decimal places for money.

$7.5 = $7.50

For every hour he works over 40 hours, he is paid an additional $7.50.
