Answer:
I assume your asking who's is better and why?
Step-by-step explanation:
Ralph has stated that for 1 shirt it will cost
$7.50 + $10 shipping= $17.50
Frank says it's $10 a shirt no shipping
if you work out the cost of Ralph's up to 5 shirts using the equation
($7.50 x number of shirts ) + $10 shipping
with each equation replace number of shirts with the number 1,2,3,4 and 5
1 shirt will cost you $17.50
2 shirts will cost you $25.00
3 shirts will cost you $32.50
4 shirts will cost you $40.00
5 shirts will cost you $47.50
at Frank's shop
1 shirt will cost you $10
2 shirts will cost you $20
3 shirts will cost you $30
4 shirts will cost you $40
5 shirts will cost you $50
Frank's is better to buy no more than 4 shirts from as he's cheaper up to 4 shirts.
Ralph is cheaper for bigger orders with 5 or more shirts in them
