Caroline’s hair is 7 inches long and grows about ⅕ inch each month. Trinity’s hair is 10 inches long and grows about 1/10 inch each month. How many months will it take for Caroline’s hair to be at least as long as Trinity’s hair?
A. 7x + 1/5 ≥ 10x + 1/10 C. 7 + 1/5x > 10 + 1/10x


B. 7 + 1/5x ≥ 10 + 1/10x D. 7 + 1/5x ≤ 10 + 1/10x

B
I know this right away because notice how it says “EACH month.” When it includes each you have to have an “x” beside the number to make it each month. If you don’t have an x it will just be “a single month.”

Sorry if that’s confusing I’m bad at explaining but have a nice day:))
