Negative one would be the answer
Answer:
the think the answer is b.
Step-by-step explanation:
x represents the number of lawns weeded by Gwen and y represents the number of dogs walked by Fabio.
Gwen charges $12 each time she weeds a yard and Fabio charges $9 each time he walks a dog.
So, for x number of weeds, Gwen earned 12x and for y number of dogs walked, Fabio earned 9y.
They need at least $510 to purchase the new gaming station.
Therefore,
12x + 9y ≥ 510
Also, the number of dog walks that Fabio has scheduled should not be more than twice the number of yards Gwen has scheduled to weed.
Therefore,
y ≤ 2x
Also, Fabio will walk at least 25 dogs.
Therefore,
y ≥ 25
Hence, the constraints are:
12x + 9y ≥ 510
y ≤ 2x
y ≥ 25
<em><u>Answer:</u></em>
s = $39,340
<em><u>Explanation:</u></em>
Note: I will use the symbol "n" instead of "t" in the solution.
<u>The given formula is:</u>
s = 32,512 * (1.1)ⁿ where "n" is the number of years.
We want to get the salary after 2 years. This means that we will substitute with n = 2 in the above equation and get the value of s.
<u>This is shown as follows:</u>
s = 32,512 * (1.1)²
s = $39,339.52 which is approximately $39,340
Hope this helps :)
