Mariulka [41]

Answer:

a. $\frac{4a}{15}$

b. $225

Step-by-step explanation:

Let Mr. Scruggs got money for his birthday be 'a'

He spent $\frac{1}{5}$ of it on dog treats = a × $\frac{1}{5}$

= $\frac{1}{5}a$

remainder amount would be = a - $\frac{1}{5}a$

= $\frac{4a}{5}$

Then he divided the remainder money equally among 3 favorite charities.

$\frac{\frac{4a}{5}}{3}$

= $\frac{4a}{15}$

a. Each charity receive $\frac{4a}{15}$

b. If he donated $60 to each charity.

$\frac{4a}{15}=60$

$a=\frac{15\times 60}{4}$

a = $225

Mr. Scruggs received $225 for his birthday.
