Question

What value of "p" makes the equation true ?

Answer 1

32 × 125 = (32 × 100) + (32 × p)

32 × (100 + 25) = (32 × 100) + (32 × p)

(32 × 100) + (32 × 25) = (32 × 100) + (32 × p)

(32 × 25) = (32 × p)

p = 25

Answer 2

32 * 125 = (32 * 100) + (32 * p)
4000 - 4000 = 3200 + 32p - 4000
32p - 0 = 3200 + 32p + 32p - 4000 -32p
-32p = 3200 - 4000
-32 / -32p = -800 / -32
p = 25
