Find the straight time pay $7.60 per hour x 40 hours
gayaneshka [121]

Answer:

The straight time pay for $ 7.60 per hour and 40 work hours per week is $ 304.

Step-by-step explanation:

Let suppose that worker is suppose to work 8 hours per day, so that he must work 5 days weekly. The straight time is the suppose work time in a week, the pay is obtained after multiplying the hourly rate by the amount of hours per week. That is:

C = \left(\$\,7,60/hour\right)\cdot (40\,hours)

C = \$\,304

The straight time pay for $ 7.60 per hour and 40 work hours per week is $ 304.

Ned caught 1/3 pound of fish. Sarah caught 5/12 pound of fish. Jesse caught 1/6 pound of fish. How many in total did they catch?
cupoosta [38]
Ok so since the largest denominator is 12 we want to get the other denominators the same so it is easier to add together. Multiply 3 by 4 to get a denominator, then multiply 1 by 4 and you'll get 4/12. Then multiply 6 by 2 and then 1 by 2 and you'll get 2/12. Add all 3 of the fractions to get 11/12 pounds of fish. Hope this helps!
