Nata [24]

Answer:

The money Rachael plan to collect for the shelter is <u>$350</u>.

Step-by-step explanation:

Given:

Rachel is collecting donations for the local animal shelter.

So far she has collected $245, which is 70% of what she hopes to collect.

Now, to find the money Rachael plan to collect for the shelter.

Let the total amount Rachael plan to collect be $x$ .

Amount she collected = $245.

Percentage of amount she collected = 70%.

Now, to get the amount Rachael plan to collect we put an equation:

$70\%\ of\ x=\$245.$

⇒ $\frac{70}{100} \times x=245$

⇒ $0.70\times x=245$

⇒ $0.70x=245$

<em>Dividing both sides by 0.70 we get:</em>

⇒ $x=\$350.$

Therefore, the money Rachael plan to collect for the shelter is $350.

40 years old

Step-by-step explanation:

Let's imagine a+b=63

63-12=51 (since they were both 6 years younger)

A is double B

34+17=51

34/2=17

You need to add the 6 years back onto the mothers age - 34+6=40

40 years old
