A restaurant manager states the number of customers that enter the restaurant is equal to 4
times the number of people that buy a hotdog from the hotdog cart plus 7. The manager also
states that the number of customers that enter their restaurant is equal to 2 times the number of
people that buy a hotdog from the hotdog cart plus 50. What number of people buying a hotdog
from the hotdog cart across the street makes the equation 4x + 7 = 2x + 50 true? Round your
answer to the nearest whole number.
