Question 2.
Sylvia weighed 8 pounds when she was born.
By her first birthday, her weight had tripled.
By her second birthday, she had gained 12 more pounds.
At that time, Sylvia’s father weighed 5 times as much as she did.
What was Sylvia and her dad’s combined weight?
Sylvia and her dad’s combined weight is 216 pounds,

Explanation:
Given Sylvia weighed 8 pounds when she was born.
By her first birthday, her weight had tripled, So Sylvia
weighed on her first birthday is 8 pounds X 3 = 24 pounds,
By her second birthday, she had gained 12 more pounds means
24 pounds + 12 pounds = 36 pounds,
At that time, Sylvia’s father weighed 5 times as much as she did,
So 36 pounds X 5 =
3
36
X5
180 pounds
therefore, Sylvia and her dad’s combined weight is
180 ponds + 36 pounds = 216 pounds.

Question 3.
Three boxes weighing 128 pounds each and one
box weighing 254 pounds were loaded onto the back
of an empty truck. A crate of apples was then loaded onto
the same truck. If the total weight loaded onto the truck
was 2,000 pounds, how much did the crate of apples weigh?

The crate of apples weigh 1,362 pounds,

Explanation:
Given Three boxes weighing 128 pounds each so weight
of 3 boxes are 128 pounds X 3 =
2
128
X 3
384 pounds and one box weighing 254 pounds were
loaded onto the back of an empty truck. So now weight is
384 pounds + 254 pounds =
384 pounds
+254 pounds
638 pounds,
A crate of apples was then loaded onto the same truck.
If the total weight loaded onto the truck was 2,000 pounds,
therefore crate of apples weigh is
2,000 pounds
– 638 pounds
1,362 pounds.

Charlie’s dad read 3,256 pages – 143 pages =
3,256
– 143
3,113 pages
Now total number of pages Charlie and his parents read are
814 + 3,256 + 3,113 =
814
