Solve using the RDW process.

Question 1.

Over the summer, Kate earned $180 each week for 7 weeks.

Of that money, she spent $375 on a new computer and

$137 on new clothes. How much money did she have left?

Answer:

Kate is left with money of $748,

Explanation:

Given over the summer, Kate earned $180 each week for 7 weeks.

So Kate earned $180 X 7 =

5

$180

X 7

$1,260

Of that money, she spent $375 on a new computer and

$137 on new clothes. So Kate has spent $375 + $137 = $512,

Now money did Kate have left with is $1,260 – $512 = $748,

Solved using the RDW process as shown above.

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?

Answer:

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.

Solved using the RDW process as shown above.

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

Answer:

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.

Solved using the RDW process as shown above.
