Three workers sort 66 boxes in a day. One of the workers is three times more productive than the second worker and twice as prod
Lelechka [254]
1 worker =x

2 worker = \frac{worker1}{2}= \frac{x}{3}

3 worker = \frac{worker1}{3}= \frac{x}{3}

so:

66=x+ \frac{x}{3}+ \frac{x}{2}

66=x+\frac{2x}{6}+ \frac{3x}{6}

66*6=6x+2x+3x

396=11x

x=36

so:

worker 1 sorted 36 boxes
worker 2 sorted 18 boxes
worker 3 sorted 12 boxes

Help me please I will mark brainliest if it will let me ‼️To attend Pennsylvania state university the cost per credit is $157 an
Snowcat [4.5K]

The yearly cost for a student who took 32 credits is $5242

Step-by-step explanation:

To attend Pennsylvania state university you must pay

  • $157 the cost per credit
  • $218 the yearly fees

We need to find the yearly cost for a student who took 32 credits

Assume that the number of credits is x

∵ The cost per credit = $157

∵ The number of credits = x

∵ The yearly fees = $218

- Put them in a linear equation

∴ The yearly cost = 157 x + 218

∵ The number of credits = 32

∴ x = 32

- Substitute the value of x in the equation below

∵ The yearly cost = 157 x + 218

∴ The yearly cost = 157(32) + 218

∴ The yearly cost = 5024 + 218

∴ The yearly cost = $5242

The yearly cost for a student who took 32 credits is $5242
