Answer
|
A.If each student received 8 pencils each, how many pencils were there altogether?
|
125 x 8 =
100 x 8 = 800
20 x 8 = 160
5 x 8 = 40
800 + 160 + 40 = 1000
|
1000 pencils
|
B. If there were 25 pencils in a packet, how many packets of pencils did they receive?
|
1000 ➗25= 40
I know 25 x 4 = 100, so 1000 ➗100 = 10, so 10 x 4 = 40
|
40 packets
|
C. If the price of one packet of pencils was $12.00, how much did the store spend on the pencils?
|
$12.00 x 40 =
12 x 10 = 120
So 120 x 4 = 480
|
$480.00
