Alex buys 5 DVDs. Each DVD costs $9. If Alex receives a $2 discount on each DVD, what is the total amount of money alex apends?

LekaFEV [45]

Answer:

The total amount of money Alex spends on 5 DVD = $ 35.

Step-by-step explanation:

Total number of DVD purchased by Alex = 5

The cost of each DVD = $9

So, the total cost of purchasing 5 DVD = 5 x ( csot of 1 DVD)

= 5 x ( $ 9) = $ 45

Now , the discount if 1 DVD = $ 2

So, the total discount of 5 DVD = 5 x ( Discount on1 DVD)

= 5 x ($ 2) = $ 10

⇒ The total amount Alex spends

= Total cost of 5 DVD - Discount on 5 DVD

= $ 45 - $ 10 = $ 35

Hence, the total amount of money Alex spends on 5 DVD = $ 35.

makkiz [27]

Step-by-step explanation:

The given word problem can be transformed into Mathematical form as given below:

$4(m + 5) = 29 \\ \\ \therefore \: 4m + 20 = 29 \\ \therefore \:4m = 29 - 20 \\ \therefore \:4m = 9 \\ \therefore \:m = \frac{9}{4} \\ \huge \red{ \boxed{\therefore \:m = 2\frac{1}{4} =2.25}}$
