What is the percent of change from $300 to $200? Round to the nearest whole percent if necessary. Is the percent of change an increase
or decrease?

1. 100%, decrease

2. 50%; decrease

3. 33%; decrease

4. 33%; increase

= 33.3333% decrease

Step-by-step explanation:

(200−300)|300|×100

=−100300×100

=−0.333333×100

=−33.3333%change

=33.3333%decrease

the given equation is ,

squaring both sides, we get

x² + 49 = (x+5)²

→ x² + 49 = x² + 10 x + 25

→ 10 x = 25 - 49 →[ cancelling x² from both sides]

→ 10 x = -24

→ x = -24/10= -12/5

but , x = -12/5 does not satisfy the equation, .

so, option (4) no solution, is correct.
