Answer:
The cost of both shirts and jeans after discount is $71
Step-by-step explanation:
Given as :
The number of shirts bought = 3
The number of pair of jeans bought = 2
The cost of each shirt before discount = $12
The cost of each pair of jeans before discount = $19
The discount on total cost = $3
Let The total cost paid = $A
<u>Now, According to question</u>
Total cost of items = number of shirts bought × cost of each shirt before discount + number of pair of jeans bought × cost of each pair of jeans before discount
Or, A = 3 × $12 + 2 × $19
Or, A = $36 + $38
Or, A = $74
<u>Again</u>
Discount of $3 is applied on total cost
So, The cost of items after discount = $74 - $3
Or, The cost of items after discount = $71
Hence, The cost of both shirts and jeans after discount is $71 Answer
