Answer:
1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)
2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal
3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.

The number of contemporary titles and classic titles in Jarred DVDs collection is 2,921 and 579 respectively.
<h3>Simultaneous equation</h3>
Simultaneous equation is an equation which involves the solving for two unknown values at the same time.
- number of contemporary titles = x
- number of classic titles = y
x + y = 3,500
x – y = 2,342
Add both be equation
x + x = 3,500 + 2,342
2x = 5,842
x = 5,842 ÷ 2
x = 2,921
Substitute x = 2,921 into
x – y = 2,342
2,921 - y = 2, 342
-y = 2,342 - 2,921
-y = -579
y = 579
Therefore, the number of contemporary titles and classic titles in Jarred DVDs collection is 2,921 and 579 respectively.
