The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches. The rock then goes to secondary crushers or hammer mills for reduction to about 3 inches or smaller.

ΔY = kΔG = 1.92 (50) = $96.2. The total change in national income is thus the sum of the tax multiplier impact and the government spending multiplier impact, which is just the net change in aggregate demand multiplied by k: ΔY = kΔG -kcΔT. And because ΔG = ΔT this becomes: ΔY = k (1-c)ΔG = 1.92 (1-0.8) (50) = $19.2.
