Tammy brought 3 apps for $2.40. At the same price, how much would 10 apps cost

vitfil [10]

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

The ratio of the bake time for a pepperoni pizza (P) and a cheese pizza (C) is modeled by the equation: P = 3C - 2. A.) If a sma

Elena L [17]

Answer:

34 minutes

Step-by-step explanation:

Given:

Ratio of time for which Pepperoni pizza and cheese pizza should be baked is given as:

$P = 3C - 2$

Where $P$ is the time for which pepperoni pizza should be baked and

$C$ is the time for which Cheese pizza should be baked.

Also, it is given that a small Cheese pizza should be baked for 12 minutes.

In other words, we are given that: $C=12\ min$

To find:

For how long small pepperoni pizza should be baked ?

In other words,

$P=?$

Solution:

Let us put the value of $C$ in the equation of the model.

$P = 3C - 2$

$\Rightarrow P = 3\times 12 - 2\\\Rightarrow P = 36 - 2\\\Rightarrow P = \bold{34\ min}$

Therefore, a small pepperoni pizza should be baked for 34 minutes.
