Answer:
She started with $6.00.
Step-by-step explanation:
1. This problem is meant to have you work backwards from the information given. Firstly, it is important to write all the expenses and earnings she had to her weekly earnings.
Starting Amount = ?
- $0.45 (candy bar)
- $2.50 (pen)
+ $.200 (mom)
End Total = $5.05
2. With this information, this next step will be much easier. With this process, you can now use inverse operations to undo the last few equations.
Firstly, $2.00 given by her mom will be subtracted from $5.05.
Secondly, with our new total of $3.05, $2.50 from purchasing the pen will be added to this amount. This leaves you with $5.55.
Lastly, the $0.45 cents she spent with the candy bar will be added to the $5.55.
This leaves the starting amount to $6.00.
3. She started with $6.00

Answer:
The high school art teacher has 468 boxes in total and the elementary school art teacher has 1,664 boxes in total.
Step-by-step explanation:
1. Collect Information.
High School Teacher: 9 cases of crayons + 52 boxes per case
Elementary School Teacher: 16 cases of crayons with 104 boxes per case
2. Multiply the number of cases by the boxes per case to get the number of boxes that each teacher has in total.
High School: 9 cases × 52 boxes = 468 boxes in total
Elementary School: 16 cases × 104 boxes = 1,664 boxes in total
3. State your answer.
The high school art teacher has 468 boxes in total and the elementary school art teacher has 1,664 boxes in total.
4. Is my answer reasonable?
Yes, my answer is reasonable for multiple reasons:
- The elementary school art teacher had more cases and more boxes so it would only make sense that the total number of boxes which the elementary school art teacher has would be greater than the total number of boxes which the high school art teacher has.
- Using common knowledge of 50 × 9 being equal to 450 (If this isn't common knowledge then remember that 5×9=45 and that you could just bring down the 0 from the 50 and the answer would be 450) you could tell that the answer would be a little more than 450 and knowing that 50×10=500 you would know that it would also be less than 500. 468 falls in between of 450 and 500 so my answer here is reasonable.
- Using common knowledge of 16×100 being equal to 1,600 and 17×100=1,700 you could tell that the answer would be greater than 1,600 and less than 1,700. 1,664 falls in between of 1,600 and 1,700 so my answer here is reasonable.
