The equation with (x) in dogs and (y) in dollars is 
First, you must set up your equation.

Then, you must add like terms to simplify the equation

Answer:
7(3+7)
Step-by-step explanation:
21+49=70
3+7=10
7*10=70
Colby and Cheryl work in different local supermarkets. Colby regu-
larly earns $8.90 per hour, and he is paid time-and-a-half for each
hour of overtime he works. Cheryl regularly earns $7.10 per hour,
and she is paid double time for an hour of overtime. Who earns
more for one hour of overtime? How much more?
Answer:
2.35 calls
Step-by-step explanation:
The presented scenario can be modeled by a Poisson distribution with an average number of calls (μ) of 5.5 during the noon hour on Mondays.
Therefore, the standard deviation for the number of calls received, X, is given by:

The standard deviation of X is 2.35 calls.
given:
she had: $35.13
+ her mom gave her: $7.50
+ she was paid $10.35
- add all of these up for total.
35.13 + 7.50 + 10.35
= $52.98
<em>look back at the answer i posted before for explanations. the answer for this would be 4/14, which is simplified to 2/7.</em>
