Answer: Cost of item with free shipping is cheaper than 15% coupon off.
Step-by-step explanation:
Since we have given that
Cost of item = $56
Amount for shipping = $9.25
Rate of coupon for off = 15%
Amount from coupon is given by
\(\dfrac{15}{100}\times 56\\\\=0.15\times 56\\\\=\$8.4\)
So, 8.4<9.25
amount they have to pay if there is free shipping is given by
\(56-9.25\\\\=\$46.75\)
Amount they have to pay if there is 15% off is given by
\(56-8.4\\\\=\$47.60\)
Hence, Cost of item with free shipping is cheaper than 15% coupon off.
