Hi There!
Answer:
$24
Step-by-step explanation:
= 1/4 + 1/3
= 3/12 + 4/12
= 7/12
7/12a + 8 = 22
Subtract 8 to both sides of the equation.
7/12a + 8 - 8 = 22 - 8
Simplify
7/12a = 14
Switch
a = 12/7 * 14
Simplify
a = $24
Hope This Helps :)

The appropriate hypotheses for this test are :
- Erica filled 70
- Jen filled 10
- Heather filled 10
- Tonya filled 10
<h3>Meaning of hypothesis</h3>
A hypothesis is a statement that proposes a result that will be tested to get a verified result.A hypothesis is not hundred percent true, that is why it is always put to test. Hypothesis is singular while hypotheses is plural
Making a hypothesis in this case is an attempt to predict an answer or result that will be verified by doing the experiment.
We can conclude by saying that a hypothesis is not hundred percent true.
