Remember:
Standards 7.EE.A.1 and 7.EE.A.2: add, subtract, factor and expand linear expressions with rational coefficients, and rewrite expressions to see meaning.
Like terms have the same variable part; combine them by adding or subtracting coefficients.
Distributive property: \(a(b+c)=ab+ac\); factoring is the same step run backward.
Subtracting a quantity changes the sign of every term inside it.
Rewriting \(p+0.05p\) as \(1.05p\) shows that a 5% increase is the same as multiplying by 1.05.
