Answer:
<u>We bought 3 specialty pens and 5 standard</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Standard pencils cost $0.85
Specialty pencils cost $1.25
You buy 8 pencils for $8
2. How many specialty pencils did you buy?
Number of specialty pencils = x
Number of standard pencils = 8 - x
Let's write our equation to solve for x:
0.85 (8 - x) + 1.25x = 8
6.8 - 0.85x + 1.25x = 8
0.4x = 8 - 6.8
0.4x = 1.2
x = 1.2/0.4
x = 3 ⇒ 8 - x = 5
<u>We bought 3 specialty pens and 5 standard</u>
This equation has already been factored as far as possible. To find the roots m, first let 2m+3=0 and then solve for m: -3/2. Next, let 4m-3=0 and solve for m.
7.50 X 315 =2362.50 at the lower price
7.75 X 315 = 2441.25 at the higher price
subtract 2362.50 from 2441.25 you get 78.75
