Question 1.
Jeremy counted from $280 to$435. Use the number line to show a way that Jeremy could have used ones, tens, and hundreds to count.

435 – 280 = 155.

Explanation:
In the above-given question,
given that,
model the count using ones, tens, and hundreds.
155.

The total amount of money in the group = $532. Explanation: In the above-given question, given that, there are 5 100 – dollar bills. 3 10-dollar bills. 2 1-dollar bills. 5 x 100 = 500. 3 x 10 = 30. 1 x 2 = 2. 500 + 30 + 2 = 532. so the total amount of money in the group =$532.

Question 2.
Show one way to count from $82 to$512.

512 – 82 = 430.

Explanation:
In the above-given question,
given that,
model the count using ones, tens, and hundreds.
430.
4 x 100 = 400.
3 x 10 = 30.
0 x 1 = 0.
400 + 30 + 0 = 430.

Question 3.
Use each number line to show a different way to count from $580 to$994.

994 – 580 = 414.

Explanation:
In the above-given question,
given that,
model the count using ones, tens, and hundreds.
414.
4 x 100 = 400.
1 x 10 = 10.
4 x 1 = 4.
400 + 10 + 4 = 414.

Question 4.
Draw and solve.
Julia wants a bike that costs $75. She needs to save$25 more to have enough money to buy it. How much money does Julia already have?
