Can someone help me with 42!

Anna earns $4 more than Elsa. First, take a look at the time intervals in Anna's chart. It skips a number. So, Anna earns $28 every 2 hours. Meaning that every hour she earns $14. Elsa earns $10 per hour because the equation tells you that. Therefore, Anna earns $4 more than Elsa per hour.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
