HELP..Maya spent 40% of her savings to pay for a bike that cost her $85 how much money was in her savings to begin with?

Answers

If 40% or .4 of her savings is $85 then we can write the equation .4s=$85 (s being the original amount in savings)
Divide both sides by .4 to get s= $212.50 as the original amount that she had

$85 is 40% of her savings.

So,

40% of x is egual to $85
40/100x = 85
0,4x = 85
x = 85 / 0,4
x = 212,5

$ANSWER = \$ 212,50$

Most likely to describe the change received from a cash purchase? A: Whole number
B: Negative numbers
C: Rational numbers

Answers

Answer:

C: Rational numbers

Step-by-step explanation:

The change received in a cash purchase, if given in £ (or $) would most certainly be a Rational number (that is a number that can be represented as a/b where a and b are coprimes). However if measured in p (or cents) then the answer would be whole numbers.

You cannot go wrong with option C as whole numbers (integers) are a subset of rational numbers. That is, all whole numbers are rational numbers.
