Step-by-step explanation:
Answer:
578.50
Step-by-step explanation:
The worker worked 40 hours at 13 dollars
40 * 13 =520
Then they worked 3 hours at 13(1.5) or 19.50
3*19.50 =58.5
The total amount of money earned is regular time plus overtime
520 + 58.5 =578.50
Answer:

Earnings = 5 + 7.50x You want to earn 50.00
50 = 5 + 7.50x Set up equation
45 = 7.50x Subtract 5
45/7.50 = (7.50/7.50) x Divide by 7.5
x = 6
You need to work 6 hours.
Answer:
31/8
Step-by-step explanation:
3/1/4 - (-5/8)
13/4 + 5/8
find Lcm of 4 and 8 = 8
multiply their common factors with numerators.
13*2 + 5*1 = 31
=31/8 or 3/7/8 or 3.875
