sanita is buying 5 posters that are all the same price. the store has a sale that takes $3 off the regular price of each poster. she pays a total of $63. she wants to know the regular price of one poster

$15.60

Step-by-step explanation:

So, if Santia buys all five posters and pays $63 then we have to first find the value of 1 poster that is on sale so:

63 ÷ 5 = 12.6.

Now that we know how much 1 poster on sale costs we need to add the back that which was was taken off due to the sale:

12.6 + 3 = 15.6

So 1 poster at original price is $15.60

$15.6

Step-by-step explanation:

Sanita pays $63 for 5 posters that are $3 off each, if you divide 63 by 5 you will get $12.6, so you have to add $3 to $12.6 to get 15.6 which was the original price of one poster.

the answer is 31.27mph
