Answer:
$7.39 per mug before sale price
Step-by-step explanation:
Divide $28.20 by 5 = 5.64
5.64 plus 1.75 equals $7.39.
Each mug was $7.39 before the sale.

6/3 = 2
y=3×-11
y=m+c
m=7-1÷6-4
m=6÷2
m=3
y=3+c
7=3(6)+c
7-18=c
-11=c
x=45
add (3x-9)+30+24=180
subtract 30 and 24 from both sides
(3x-9) = 126
+9 on both sides
3x=135
divide by 3 on both sides
