The answer to your question is 80 pounds pounds pounds
Y=2.5x+30 - the function where y = the total cost and x = the # of notebooks.
40 = 2.5x + 30 - Plug 40 into y and solve
10= 2.5x
x = 4, the number of notebooks she bought
s = 6 + e
s + e = 28
We can use this system of equations to find the exact values of s and e.
We have a current value of s, so we can find the exact value of e now.
e + e + 6 = 28
<em><u>Combine like terms.</u></em>
2e + 6 = 28
<em><u>Subtract both sides by 6.</u></em>
2e = 22
<em><u>Divide both sides by 2.</u></em>
e = 11
Now we have an exact value of e, and can solve for the value of s.
s = 6 + 11
s = 17
