Disco Maths
24 children went to the school disco. How much did the school collect from the entry fees?
24 x 9 =
4 x 9 = $36
10 x 9 = $90
10 x 9 = $90
24 x .70 = $22.40
$36 + $90 + $90 + 22.40 = 238.40
42 had snacks . How much money did the school collect for supper?
42 x $6.80 =
2 x 6 = 12
40 x 6 = 240
2 x .80 = 1.60
40 x .80 = $34.00
$12 + $240 + 1.60 + $34.00 = $287.60
How much money did the school collect altogether?
$238.40 + $287.60 =
$200 + $200 = $400
$30 + $80 = $110
$8 + $7 = $15
.40 + .60 = $1.00
$400 + $110 + $15 + $1.00 = $526.00
