There are 25 blue and 35 red marbles in a bag. Find the total number of marbles in the bag.
a.
60
b.
70
c.
57
d.
65


Solution:

Total number of marbles in the bag = number of blue marbles + number of red marbles

25 = 20 + 5
35 = 30 + 5
[Break the numbers into tens and ones.]

(20 + 30) + (5 + 5)
[Add the tens and ones separately.]

= 50 + 10 = 60
[Add the two sums.]

So, there are a total of 60 marbles in the bag.

Steve has traveled 8 kilometers in the morning, 7 kilometers in the afternoon, and 9 kilometers in the evening. Find the total distance that Steve traveled during the day.
a.
14 km
b.
24 km
c.
22 km
d.
27 km


Solution:

Total distance traveled during the day = Distance traveled in the morning + Distance traveled in the afternoon + Distance traveled in the evening.

= 8 + 7 + 9 = 24
[Substitute the values and add the ones.]

So, Steve traveled 24 kilometers during the day.

Michael had $72 with him. He made $18 by delivering pizzas. How much money does he have now?
a.
$92
b.
$90
c.
$80
d.
$54


Solution:

Amount Michael has = 72 + 18

72 = 70 + 2
18 = 10 + 8
[Break the numbers into tens and ones.]

(70 + 10) + (2 + 8)
[Add the tens and ones separately.]

= 80 + 10 = 90
[Add the two sums.]

So, Michael has $90.
