Question

3) The Blackweld family is shopping for school uniforms. Pants cost $5

more than skirts. Six skirts cost $4 less than 4 pairs of pants. How much
does 1 skirt cost?

Answer 1

• $8

Explanation:

• Let the pants cost = p
• Skirts cost = s

We got equations

• p = s + 5
• 6s = 4p - 4

Substituting p and solving for s

• 6s = 4(s + 5) - 4
• 6s = 4s + 20 - 4
• 6s - 4s = 16
• 2s = 16
• s = $8
