Answer:
The answer is $8.00.
Step-by-step explanation:
First, you have to find how much for each app so you have to divide by 3 :
3 apps = $2.40
1 app = $2.40 ÷ 3
1 app = $0.80
Next, you have to multiply it by 10 :
1 app = $0.80
10 apps = $0.80 × 10
10 apps = $8.00
Answer:
Step-by-step explanation:
Lets Price of a DVD is fixed i.e. 15
and One CD price is 5 (Not fixed)
In First situation
2 DVDs and 1 CD cost = 35 as given
2 x 15 + 5 = 35
Lets one CD price is 7.5
In Second situation
2 x 15 + 2 x 7.5 = 45
Its mean CD price may be between 5 to 7.5
In asked scenario, Martin has 50
1 DVD and 3 CDs?
1 x 15 + 3 x 7.5 = 37.5
37.5 is lesser than 50
Hence Martin has enough to buy 1 DVD and 3 CDs.

Answer:$0.36
Step-by-step explanation:
0.42 devided by 7= 0.06
0.06 times 6= 0.36
Let us assume number of n.
The number is decreased by 15.
Decreasing by 15 means, we need to subtract 15 from that number.
So, it would be come n-15.
Now, it is said that the number would become less than 2.
So, we need to setup an inequality:
n-15 is less than 2.
<h3>n-15 < 2 : required inequality .</h3>
Adding 15 on both sides, we get
n-15+15 < 2+15
n < 17.
<h3>So, we could say the number would be less than 17.</h3>
