math problem what's order

Question

Ace Hardware sells boxes of wrenches ($110) and hammers ($309). Howard ordered 27 boxes of wrenches and hammers for $5,955. How many boxes of each are in the order?

 

Boxes of hammers
Boxes of wrenches

Answer 1

w = number of boxes of wrenches at $110 per box

h = number of boxes of hammers at $309 per box

w + h = 27

110w + 309h = 5955

You have a system of 2 equations in 2 unknowns w and h, which you can solve by substitution, elimination, matrix methods, or Cramer's rule. Using Cramer's rule, I get

w = 12

h = 15
