(b) $ 23.38
(c) The first store is selling a shirt for $11 , while the second store, store B will sell a shirt for $11. 69 after the 10% discount
(d) Store A has better deal , even without any discount , a shirt still cost $ 11 , and store B even with the discount , a shirt is still $11.69
Explanation:
(a) Since two shirt cost $22 , then a shirt will cost $22/2 , which is $11
(b) sales off is 10% , that is 10% of $12.99
= 10 / 100 x 12.99
= 1.299
≈$1.30
This means that a shirt will cost : $12.99 - $1.30
= $11.69
cost of two shirt will then be $11.69 x 2 = $23.38
(c) With the discount store B is offering , the cost of a shirt is still more expensive than store A that is not giving any discount.
(d) Store A definitely has the better deal because the cost of a shirt is cheaper than that of store B
