A bag of popcorn at the movies costs $8 and a soda costs $3. A group of students buys 5 more sodas than popcorn spends a total of $125 on soda and popcorn. Which system of equations can be used to find b, the number of bags of popcorn, and s, the number of sodas?

b – s = 5
8b + 3s = 125
s – b = 5
3b + 8s = 125
s – b = 5
8b + 3s = 125
b – s = 125
3b + 8s = 5

A laminated table top consists of layers of two types of wood. The first type is a hardwood, and the layers of hardwood are 2 millimeters thick. The second type of wood is a softwood whose layers are 3 millimeters thick. There are a total of 12 layers that make a table top that is 28 millimeters thick. Which of the following system of equations can be used to determine h, the number of hardwood layers, and s, the number of softwood layers in the table top?

2s + 3h = 28
s + h = 12
2s + 3h = 12
s + h = 28
3s + 2h = 28
s + h = 12
3s + 2h = 12
s + h = 28

Wisely owns a computer shop that sells computers and computer parts. Wisely purchases mice for the computers at m dollars each and sells them for g dollars each. Last year Wisely purchased a total of 420 mice and sold a total of 380 mice for a profit of $1,780. This year, Wisely has purchased 200 mice and has sold 120 mice for a profit of $360. Which system of equations can be used to determine the values of m and g? (Assume that in the world of Wisely, mice are consumable products and no mice were left over from last year to this year ;) )

Which system of equations can be used to determine the values of m and g? (Assume that in the world of Wisely, mice are consumable products and no mice were left over from last year to this year ;) )
420g – 380m = 1780
200g – 120m = 360
420g – 380m = 360
200g – 120m = 1780
380g – 420m = 1780
120g – 200m = 360
380g – 420m = 360
120g – 200m = 1780

To graduate high school, a freshman needs a total of 26 credits. Classes are either .5 or 1 credit each. A high school student needs a total of 28 classes. Which system of equations can be used to determine m, the number of .5 credit classes, and n, the number of 1 credit classes the student can take to graduate high school?

Which system of equations can be used to determine m, the number of .5 credit classes, and n, the number of 1 credit classes the student can take to graduate high school?
m + n = 28
m + 2n = 26
m + n = 26
.5m + 2n = 28
m + n = 28
.5m + n = 26
m + n = 26
.5m + n = 28
answer all of the questions
1. b – s = 5
8b + 3s = 125
2. 2s + 3h = 28
s + h = 12
3. 420g – 380m = 1780
200g – 120m = 360
4. m + n = 28
.5m + n = 26
