Admission to the zoo costs $4 for adults and$2 for kids. The total bill for your entire extended family was \$30. This scenario can be modeled by the equation 4a + 2k = 30. Which is not a possible combination of adults and kids? 5 adults and 5 kids 4 adults and 7 kids 7 adults and 1 kid 3 adults and 6 kids

for example you have equation 4a + 2k = 30 5 adults and 5 kids 4(5) + 2(5) = 30 20 + 10 = 30 30 = 30 true so that is ok

ok, since you have 99 I guess I can give you the answer 3 adults and 6 kids 4(3) + 2(6) = 30 12 + 12 = 30 24 = 30 NOT GOOD
