Let x be Chloe's rate before the raise. The rate now is the rate before plus 10% of the rate before the raise: $x + 0$ .

$10 x = 22$

1) $10 x = 22$

$x = \frac{22}{1.10}$

$x = 20$
Hence, Chloe earns $20 an hour before the raise.
Let x be sale price of the bicycle.
The sale price is the regular price minus 25% of the regular price:

$x = 396 - 0.25 (396)$

$x = 396 - 99$

$x = 297$
Hence, the sale price of the bicycle is $297.
