Answer:

25 pounds cashews
15 pounds peanuts

Step-by-step explanation:

Let c represent the number of pounds of cashews in the mix. Then 40-c is the number of pounds of peanuts. The total cost of the mix is ...

10c +2(40 -c) = 7(40)

8c +80 = 280 . . . . simplify

c +10 = 35 . . . . . . . divide by 8

c = 25 . . . . . . . . . . subtract 10

40-c = 40-25 = 15 . . . . pounds of peanuts

25 pounds of cashews and 15 pounds of peanuts should be used in the mix.

A service attendant is paid time and a 1/2 for working over 40 hours per week last week. The attendant work 47 hours and earned

devlian [24]

Write and solve an equation:

Total earnings = $782.75 = s(40 hrs) + 1.5*s*(7 hrs)

Then 782.75 = 40s + 10.5s = 50.5s

Dividing both sides by 50.5: s = 15.5. The attendant's regular hourly wage was $15.50.
