Mika’s gym allows her to bring 3 guests for free. After the first three, she must pay $7 per guest. How many guests, g, can she bring to the gym if she pays $42?

Three of these equations give the correct value of g. Which equation does NOT?

CLEAR CHECK

7g = 63



7(g – 3) = 42



7g – 3 = 42



g = 9

1 answer

The equation that does NOT give the correct value of g is:

7(g – 3) = 42
