 |
- 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?
14 + 14 = 28 61 - 28 = 33 33 ÷ 3 = $11
- 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 so 12 x 27 = 324 so 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 r 3 16 x 7 = 112 112 x 11 = 1232 1232 + 33 = $1265
