Martha is buying two shirts that each cost $20. at a local store. She is considering two options to purchase the shirts.
Option A: Use the store sale- buy one shirt and get a second shirt at 50% off the original price.
Option B: Use a coupon for 30% off the entire purchase.
Martha will also pay 7% tax on her purchase.
Which option will cost less money?
Option A:
The original price of one shirt is $20. So, buying two shirts at full price would cost $20 + $20 = $40.
With option A, Martha would get a second shirt at 50% off the original price, which means she would pay 0.5 * $20 = $<<0.5*20=10>>10 for the second shirt.
So, with option A, Martha would pay $20 + $10 = $<<20+10=30>>30 for the two shirts.
Option B:
With option B, Martha would get 30% off the entire purchase. So, she would pay 0.7 * ($20 + $20) = $<<0.7*(20+20)=28>>28.
Both options include 7% tax on the purchase price. So, Martha would pay an additional 0.07 * ($30) = $2.10 for option A, and an additional 0.07 * ($28) = $1.96 for option B.
Therefore, the total cost for option A is $30 + $2.10 = $<<30+2.10=32.10>>32.10, and the total cost for option B is $28 + $1.96 = $<<28+1.96=29.96>>29.96.
Therefore, option B will cost less money.
Can you explain option b
Certainly! In option B, Martha will use a coupon for 30% off the entire purchase. This means she will receive a discount on both the price of the shirts.
The original price of each shirt is $20. So, the total cost for both shirts is $20 + $20 = $40.
With the 30% off coupon, Martha will receive a discount of 30% on the entire purchase. To calculate this discount, she can multiply the original price of $40 by 0.3 (which is the decimal form of 30%): $40 * 0.3 = $12.
So, with option B, Martha will get a discount of $12 on the total purchase price of $40. To find the final cost, Martha will subtract the discount from the total purchase price: $40 - $12 = $28.
However, it is important to note that Martha will also need to pay 7% tax on her purchase.
To calculate the tax, Martha can multiply the final cost of $28 by 0.07 (which is the decimal form of 7%): $28 * 0.07 = $1.96.
Therefore, with option B, Martha will pay the final cost of $28 + $1.96 = $29.96.
