解答ステップ

Translate the problem into an equation:

45000 = x + 0.15 x

45000 = x + 0.15 x : x = \frac{900000}{23}

Translate the problem into an equation:

y = 0.15 \cdot \frac{900000}{23}

y = 0.15 \cdot \frac{900000}{23} : y = \frac{135000}{23}

\frac{135000}{23} = 5869.56521 \dots

Tax amount : 5869.56521 \dots
