A single kabob stick has 4 cubes of beef. A slab of beef that costs $25 can be cut into 80 cubes. How much must Simon spend to make 40 kabob sticks?
One slab of beef can make 80/4 = <<80/4=20>>20 kabob sticks.
To make 40 kabob sticks, Simon needs 40/20 = <<40/20=2>>2 slabs of beef.
Simon must spend $25 x 2 = $<<25*2=50>>50
