 |
- 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 x 2 = 28
$61 - $28 = $33
$33 divided by 3= $11
So it costs $11 per child under 12..
- 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?
100 x 10 = 1000 and 12 x 27 = 324 so 1000 + 324 = $1,324
- 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 divided by 9 = 16 r 3
16 x 7 = 112
112 x 11 = 1,232
1,232 + 33 = $1,265
