Answer:
No solution
Step-by-step explanation:
Step 1: Write out equations
y = -1/4x + 2
3y = -3/4x - 6
Step 2: Substitution
3(-1/4x + 2) = -3/4x - 6
Step 3: Distribute
-3/4x + 6 = -3/4x - 6
From here, we can see that we have the same slope but different y-intercept. This means that the 2 lines are parallel and therefore never intersect.
Alternatively, you could graph the equations and see that the 2 lines are parallel and never intersect.
4500 tons, which by the way is very unlikely
Firstly we need to count how much did the employees earn after the raises:
4% from $41,000 =
= 4/100 * 41,000 =
= 4 * 410 =
= 1644
4,5% from 43,700 =
= 45/1000 * 43,700 =
= 45 * 43,7 =
= 1966,5
3% from 39,700 =
= 3/100 * 39,700 =
= 3 * 397 =
= 1191
Now we need to sum up all the raises:
1644 + 1966,5 + 1191 = 4801,5
So now we can clearly see that answer A ($4,802) is the closest one to the total of all three raises.
