Sewing patterns recommend buying extra fabric in case of mistakes. Jessica bought 5 yards of fabric, plus 20% extra. Dan bought 3 yards of fabric, plus 25% extra. Who bought more fabric? How much more?

Answer:

Jessica bought 2.25 yards more fabric.

Step-by-step explanation:

For Jessica we will consider 5 to be 100% which is 1 in decimals (100÷100=1) of what she bought originally and since she bought 20% (which is 0.20 in decimals 20÷100=0.20) more then we have 100% + 20% = 1 + 0.20 = 1.20 of our original 5.  So now we multiply 5×1.20=6, so Jessica bought 6 yards.

Similarly we have Dan who bought 3 yards plus 25% more.  Well 25% is 0.25 and so: 100% + 25% = 125% = 1.25.  Now, we will multiply 3 × 1.25 = 3.75 yards.  Therefore, Jessica bought more fabric.  How much more? 6 - 3.75 = 2.25 yards more.
