Adding all of their work together we get 4 hr + 3 hr + 1 hr = 8 hrs of work.

If the payment for 8 hrs of work is R400 then the payment per hour of work is R400 รท 8 = R50 per hr.

Phumelo then should receive 4 hr x R50/hr = R200

Ivan should receive 3 hr x R50/hr = R150

and John for 1 hour of work should receive R50

The students spent a total of:

4 hours + 3 hours + 1 hour = 8 hours on the job.

Phumelo worked 4 of the 8 hours so he should receive 4/8 of the \$400:

Phumelo's Pay = (4/8)*(\$400) = ???

Ivan worked 3 of the 8 hours, and should get (3/8) of the pay:

Ivan's Pay = (3/8)*(\$400) = ???

John worked the remaining 1 of 8 hours.  How much of the \$400 should he get?
