Answer:
For part a. we need to find the total and apply the discount. The answer for part a is $71.
For part b. we need to subtract $3 from each individual price and then find the total. The answer for part b is $59.
Explanation:
Part a: if each shirt is $12 and she wants to buy 3 shirts, then the cost will be 3 X $12 = $36.
If each pair of jeans is $19 dollars and she wants to buy two pairs, then the cost will be 2 x $19 = 38.
Add the two costs together to get the total cost of the purchase without the discount. $38 + $36 = $74.
Now subtract $3 from the total to get the answer for part a:
$74 - $3 = $71
Part b. If the original cost of the shirt is $12 and a $3 discount is applied to each shirt, each shirt will now cost $9. If Pani buys the three shirts at the discounted price, the cost of the shirts will be 3 x $9 = $27.
If the original cost of the jeans is $19 and a $3 discount is applied, the jeans will now cost $16. If Pani buys the two jeans at the discounted price, the cost will be 2 x $16 = $32.
Add the costs together to get the amount she would pay: $27 + $32 = $59.
hope this helps =)
