based on the number of mice that took part in the experiment, the total number of mice that had at least one effect is 20 mice.
<h3>how many mice had a health effect?</h3>
15 mice had at least 1 tumor while 4 mice had both a tumor and respiratory failure.
the number of mice with just a tumor is:
= 15 - 4
= 11 mice
the number of mice with respiratory failure alone is:
= 9 - 4
= 5 mice
the mice that had at least one symptom is:
= 11 + 5 + 4 mice with both
= 20 mice
question is:
what are the number of mice with at least one effect?

300%= 9,000
20%= 60
5%= 15
9,000+60+15= 9,075
answer: £9,075
Without context, I can only assume that<em> e</em> is a variable, which means that it is an unknown number. Any letter can be a variable, and you solve for that variable by isolating it on one side of the equation. Example: e = 12
