• A. $31\frac{1}{2}$
• B. $32\frac{1}{2}$
• C. $34\frac{1}{2}$
• D. $25\frac{1}{2}$

Answer 1

The correct option is A $31\frac{1}{2}$

Per hour Money earned per hour $=\$1.5$
Since he works 3 hours in a day
So, moeny earned per day $=3\times 1.5=\$4.5$

Money earned in week $=7\times 4.5$
$=\$31.5$

Convert this decimal into mixed numbers
So, $31.5=31+0.5=31+0.5\times \frac{10}{10}$
$=31+\frac{5}{10}$
$=31+\frac{1}{2}$
$=31\frac{1}{2}$
Hence, the money earned by Michael in a week $=31\frac{1}{2}$ dollars
