121 is your answer for 42 hope this helps
Let $A be the cost of $q of merchandise under plan A and similarly $B under plan B.
A=120+0.80q, B=40+0.90q
When A=B, 120+0.80q=40+0.90q, 80=0.10q, q=80/0.10=$800.
So you would need to buy $800 of merchandise.
A=B=120+640=40+720=$760 for each plan.
Your ultimate goal is to get the variable secluded all by itself. You'll have to use the opposite operation to do this and remember, what you do to one side, you have to do to the other.
1. 9s + 3 = 57
2. Subtract 3 from each side. This will result in 9s = 54
3. To undo the multiplication of 9s you'll divide both sides by 9. 9s/9 = 54/9
4. The ending result is: s=6
5. Go back and check your work by substituting it in your original equation.
Step-by-step explanation:
the diameter is 2 times the radius.
so,
12.7×2 = 25.4
so, B is right.
