-how do i set up the equations??

Answer 1

Favorite Answer

let x be: the amount of pay per week

$120 + ($70 X 2)= x

$120 + $140 = x

x= $260

hope this would help :)

Answer 2

They've asked you to set up the system of equations, not solve the problem.

Let 'a' be the number of chef, and 'b' be the number of waiters hired.

Then,

Cost of hires = 120a+70b ......(i)

b >= 2a (b is greater than or equal to 2*a) or,

b-2a >= 0 .....(ii)

(i) and (ii) describe the system of equations.
