Ashley has 36 coins totaling $4.20 in quarters and dimes. How many of
each coin does she have?

For a $45 purchase the discount would be $-4.5

the sales price $40.5

For a $110 purchase the discount is  $-11

The sales price $99

Step-by-step explanation:

To find the discount on an item first multiply the original cost of the item by the percentage discounted. in this case,

$45 × 0.10 = $4.5

$110 × 0.10 =$11

$4.5 and $11 are respective discount amounts

now simply subtract the amount of the discount from the original price

$110 - $11 = $99

$45 - $4.5 =  $40.5

These are your final sale prices after discount.
