The three students whose individual number of shirt owned sums up to 20 are <em>Will, Mandy and Cindy</em>.
<u>Given the information about the number of t-shirts owned by 4 students</u> :
- Will 4
- Mandy 7
- Greg 12
- Cindy9
<u>To obtain the which three students have shirts which sums up to 20</u> ;
- We could sum the number of t-shirts owned by any of the three students and see if it gives a value of 20.
- From the data, the 3 students who have the least number of t - shirts have a total of 20 t - shirts
<em>Will + Mandy + Cindy</em>
4 + 7 + 9 = 20 students
Therefore, the three students whosw shirts sums up to 20
are <em>Will, Mandy and Cindy</em>.

To do part A and B, note that functions are distributive, meaning (h+t)(x) = h(x)+t(x) and (h•t)(x) = h(x)•t(x).
Giving:
A: (h+t)(x) = 2x - 5 + 6x + 4 = 8x - 1
B: (h•t)(x) = (2x - 5)•(6x + 4) = 12x^2 - 22x - 20
C: h[t(x)] = 2[t(x)] - 5 = 2(6x + 4) - 5 = 12x + 3
130 is closer to 100 than 200, so it is 100
I think it’s 51.6% because 8.3% interest at the rate of 6 years is just 8.3 multiplied by 6 which is 51.6
