You worked from 2:30pm - 8:45pm with a 1/2 hour lunch break your hourly wage is $7.50/hour how much did you earn

levacccp [35]

Find out how many hours you worked first.

2:30 pm-8:45 => 6:15 hours

But they say that you take a break of 1/2 hour

6:15- 0:30= 5:45 hours

Convert all the data into hours. 5 hours + 45/60 hours

Multiply data with given hourly wage.

5x$7.50=$37.5

(45/60)x7.50=$5.625

In total, you earn (37.5+5.625)=> $43.125

Hope I helped :)

3a/4+2a/3-a/12 a. a/3 b. 4/3 c. (4a)/3

insens350 [35]

Answer: C

Step-by-step explanation:

$\frac{3a}{4}+\frac{2a}{3}-\frac{a}{12}$

Find the least common denominator of 4, 3, and 12.

4-3-12 | 3

4-1-4 | 4

1-1-1 |-------- 12

The first fractions needs to be multiplied by 3, and the second fraction, by 4

$(\frac{(3a)*3}{(4)*3})+(\frac{(2a)*4}{(3)*4})-\frac{a}{12}$

Solve;

$\frac{9a}{12}+\frac{8a}{12}-\frac{a}{12}$

Add the fractions with positive signs and subtract the one with negative sign.

$\frac{(9a+8a)-a}{12}$

Solve;

$\frac{17a-a}{12}=\frac{16a}{12}$

Simplify by 4;

16/4=4

12/4=3

$\frac{4a}{3}$
