Step-by-step explanation:
First,
(A intersect B) = {1,2,4,5} intersect {1,3,5,7}
= {1,5}
Now,
A'n B = (A) - (A intersect B)
= {1,2,4,5} - {1,5}
= {2,4}
1. Yes he would be able to but the back pack and he would actually have 18 to spare. Explanation- he saves $9 a week so if he saves for 7 weeks then he will have $63 but since he only needed 45 he will have 18 to spare

Answer:
A) $15
Step-by-step explanation:
let x represent the regular price of the mirror
so, 20% of x = 3
20/100 * x = 3
20x = 300
x = 300/20
x = 15
Hence, the regular price of the mirror is $15
Set the expressions equal to each other to get 17
