ycow [4]

Answer:

9 1/3

Step-by-step explanation:

1. Make 4 2/3 into a improper fraction

4 2/3= 14/3

2. Keep, change, flip

14/3 x 2/1

3. Multiply

14/3 x 2/1= 28/3

4. Simplify

28/3= 9 1/3

(btw keep, change, flip basically means to keep the first fraction the way it is, change the division sign to a multiplication sign, then flip the second fraction so the original denominator is the new numerator, and vise versa.)

Jennie is paid $10 an hour for regular time work and $20 an hour for overtime
lyudmila [28]

Answer:

Jennie earned $300

Step-by-step explanation:

We are already given the amount of time that she works and the rate. We just need to multiply the time by the corresponding rate. She worked 22 regular hours and gets $10 for each one. That means she earned $220 just from the regular hours.

Now we need to add the overtime hours. She worked 4 hours and made $20 for each one. In total, that's $80.

220+80=300

Jennie earned $300
