Answer: $83
Explanation:
Given that,
On 1 June,
Materials purchased = 50 units
Unit price of material = $1.30
On June 15,
Materials purchased = 50 units
Unit price of material = $1.20
Total cost of 65 units:
= (Material purchased on 1 June × Unit price of material) + [(65 units - 50 units) × $1.20]
= (50 units × $1.30) + (15 units × $1.20)
= $65 + $18
= $83
