Answer:
<u><em>y=7 </em></u><u>number of hours at grocery store</u>
<u><em>x=18 </em></u><u>number of hours at baby- sitting</u>
Step-by-step explanation:
According to the information provided.
x is number of hours at baby- sitting
y is number of hours at grocery store
total number of hours worked
<em>1) </em><em>x+y =25</em>
total earn in a week
<em>2) </em><em>x*$6 + y* $9 = $171</em>
<em />
<em>from equation 1</em>
x+y=25
x= 25-y
<em>we place the above derived equation in equation 2 </em>
x*$6 + y* $9 = $171
(25-y)*$6 + y* $9 = $171
(25*6) -6y +9y =171
150+3y=171
3y=171-150
3y=21
<u><em>y=7 </em></u><u>number of hours at grocery store</u>
x= 25-y
x= 25-7
<u><em>x=18 </em></u><u>number of hours at baby- sitting</u>
Answer:
That is not a function :)
Step-by-step explanation:
You can recognize functions by seeing if it passes the <em><u>vertical line test</u></em><em><u>.</u></em> If you draw a vertical line anywhere are the grid and it crosses the equation in more then one place then it does not pass the test, and is not a function.

Answer:
715 pounds
Step-by-step explanation:
<em>FV = solve</em>
<em>PV = 600</em>
<em>I% = 6</em>
<em>K = 1, N = 3 </em>(2013 - 2016 = 3 years)
Plug it in:
<em>FV = 600 x [ 1 + (6/100 x 1)]³</em>
= 600 x ( 1 + 0.06)³
= 600 x (1.06)³
FV = 714.61, 715 to the nearest dollar.
<em>Therefore, the fee in 2016 is 715 pounds.</em>
