100 = 7 + 15.5p
the number of people he can bring to the zoo is 6
Step-by-step explanation:
Total amount to be spent = $100
Amount for parking = $7
Admission per person = $15.50
let the number of person = p
The equation:
Total amount to be spent = Amount for parking + Admission per person × number of person
100 = 7 + 15.5(p)
100 = 7 + 15.5p
Solving the equation:
100 = 7 + 15.5p
subtract 7 from both sides:
100 - 7 = 7 - 7 + 15.5p
93 = 15.5p
divide both sides by 15.5:
93/15.5 = 15.5p/15.5
p = 6
Hence, the number of people he can bring to the zoo is 6
