-138 is greater than -6(6b-7)
solution
-6(6b-7)
= -36b+42
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
