Mr. Scruggs got some money for his birthday. He spent 1/5 of it on dog treats. Then, he divided the remainder equally among his
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.

If q, s, and t are all different numbers, is q < s < t ?
inessss [21]
It very well could be, but not necessarily. What if q = 10, s = 8, and t = 6?

The statement is that q is less than s, and s is less than t (which therefore also means q is less than t).

However, when we substitute (replace) all the letters with the values we assigned them, we can find that the expression becomes:

10 < 8 < 6

This clearly isn’t right, as 10 is the greatest number there, and 8 is definitely less than 10 and greater than 6.
