Question

Admission to the movies costs $8 for adults and $4 for kids. The total bill for your entire extended family was $72. This scenario can be modeled by the equation 8a + 4k = 72. Which is not a possible combination of adults and kids?

3 adults and 12 kids
5 adults and 6 kids
7 adults and 4 kids
8 adults and 2 kids

Answer 1

Just try out each combination:)
8(3) + 4(12) = 72
8(5) + 4(6) = 64
8(7) + 4(4) = 72
8(8) + 4(2) = 72
Which is not a possible combination of adults and children?
