Answer: 144
Step-by-step explanation:
You add up the area of each side
the two triangular sides- A=BH/2 3 times 4 divided by 2 so 6 but there are two triangles so you multiply by two so 12
the bottom rectangle- A=LW 4 times 11 so 44
the top rectangle- A=LW 5 times 11 so 55
the back rectangle- A=LW 3 times 11 so 33
12+44+55+33=144
the correct answer is A
let me guess khan ? I'm using that too

Answer:
$7.6 ;
No, you will not be able to buy 3 more CDs
$9.5
$28.5
Step-by-step explanation:
Given that :
Cost of 4 CDs = $30.40
Cost per CD is equal
Sale price = 80% of original price
Price p per CD:
Cost of 4 CDs / number of CDs
$30.40 / 4
= $7.6
2)
No, you will not be able to buy 3 more CDs
If x = original price
80% of x = 7.6
0.8x = 7.6
x = 7.6 / 0.8
x = $9.5
$9.5 * 3 =$28. 5
Hence, $25 can't buy 3 CDs the next day (28.5 > $25)
