Fish food is $3.50. An aquarium is $10.00. A filter system costs $9.95. Gravel and plants are $6.25. Mike has $30.00 to spend. H
Veronika [31]

Add all the prices together:

3.50 + 10.00 + 9.95 + 6.25 = 29.70

He has 30, so he had 30 - 29.70 = 0.30 left over for fish.

Leokris [45]

Answer:

0.60

Step-by-step explanation:

Probability that the customer is not a poor risk = 1 - probability that the customer is a poor risk

Firstly, let’s calculate the probability of being a poor risk.

From the given data the number of poor risks = 14229-7362-1190 = 5677

So the probability of being a poor risk = 5677/14229 = 0.399

Thus, the probability that the customer is not a poor risk = 1-0.399 = 0.601 which to 2 decimal places = 0.60

What is unitary method?

We can solve this question by unitary method.
The unitary method is a method of finding the value of one unit and then finding the value of the required number of units. While solving a problem it is important to recognize the units and values.


In this question, 10 tacos cost $105.
Let's represent the cost of 1 taco as x
10 tacos =$ 105
1 taco = x
