Hi,

I need to a pair of simultaneous equations to solve the following.Im not asking for the answer as I can work out that my self once It has been transposed.

Existing contract...it will take 210 days if 12 painters paint a building.the company as been offered a new contract.they will make £250 extra profit per day in new contract.They are considering hiring more painters to complete the existing contract ASAP but only 3 more painters are available.

every 6 painters need 1 supervisor and each supervisor costs £90 extra per day.

a) analyse extra cost/profit for company if they decide to complete the contract with 15 painters (12 +3).

Need equations for the following...

1) 2 supervisors and 10 painters will cost £1008 per day

2) 3 supervisors and 16 painters will cost £1596 per day

find the earnings of a painter and a supervisor

Thanks.....
