- It cost the Naidoo family of 2 adults and 3 children $61 to go to the zoo. What is the missing price on the board?
2 x 14 = 28
61 - 28 = 33
33 ➗ 3 = $11 per child
- For 4 days of the week the zoo has a concession for schools. $10 each for the first 100 children and then $12 each for the others. What would a school pay if there are 127 children?
10 x 100 = 1000
12 x 27 = 324
1000 + 324 = $1324
- On a Friday evening the zoo has a special rate for school children:for every paid 7 children 2 get to go in free. What would it cost a school with 147 children?
147 - 9 = 16 r3
16 x 7 = 112
112 x 11 = 1232
1232 + 33 = $1265
