First, think about what your answer is. It isn't just how much more the store is charging, but the total amount they are charging, so instead of using just 75%, we need to use 175% to show that we also need to add on the amount they paid for it. It sounds confusing, but stay with me! Now, convert that 175% to a decimal, 1.75. Finally, multiply the starting price ($6) by 1.75.
