1.) two weavers are selling their products at a crafts fair. one weaver sells 4 blankets and 6 sweaters for $150. the other weaver sells 8 blankets and 12 sweaters for $400. do the weavers charge the same amount for blankets and sweaters? write and solve a system of equations to support your answer.
2.) re-write the system to make it easier to solve, then solve to find a solution.
y = 0.005
0.006x + 0.00812y = 0.00087

These are the answers of the following items:

(1) 
One weaver sells 4 blankets and 6 sweaters for $150.
4B + 6S = 150
2B + 3S = 75

The other weaver sells 8 blankets and 12 sweaters for $400.
8B + 12S = 400
2B + 3S = 100

Do the weavers charge the same amount for blankets and sweaters? NO
Write and solve a system of equations to support your answer.

2B + 3S = 75
2B + 3S = 100
NO SOLUTION

2.) Re-write the system to make it easier to solve, then solve to find a solution.

y = 0.005
0.006x + 0.00812y = 0.00087

y = 5
6x + 8.12y = 0.87

6x + 8.12*5 = 0.87
6x = -39.73
x = -6.62

Sorry i don't really know and i don't have time

How many groups are there?
