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>
