Answer:
Step-by-step explanation:
Let E = Erasers and P = Pencils
4E + 2 P = $16…(1)
3E + 1P = $10.50…(2)
Multiply (2) by 2 to make Pencils in (1) and (2) equal.
6E + 2P = $21…(3)
Subtract (3) from (1) to eliminate P
2E = $5 => Erasers = $2.50 each
Substitute this value for Erasers into (3)
6 * $2.50 + 2P = $21
2P = $21 - $15 = $6 => Pencils = $3
Therefore 5 Erasers + 3 Pencils cost
5 * $2.50 + 3 * $3 = $12.50 + $9 = $21.50

5⅙
+4⅚
Add integers and fractions
5⅙
<u>+4⅚
</u>
9⁶/₆
Convert the fraction to an integer
⁶/₆ = 1
Add the 1 to the 9
9 + 1 = 10 ft
