Answer:

Step-by-step explanation:
we know that
To find the the rate per studen, we need to divide the total amout spent by the number of students
so

Answer:
first three terms are
-1, -1/2 & 0
Step-by-step explanation:
here,
a=-1
and d=1/2
so
t1 = -1
t2 = a+(n-1)d= -1 +(2-1)*(1/2)=-1/2
t3= a+(n-1)d= -1 +(3-1)*(1/2) =0
None of these couples are solutions, (11, 3)(11, 3); (−1, −6)(−1, −6); (−3, 3)(−3, 3); <span>(7, 0). Perhaps the choice of answer are insufficient. we can add (1, 48) the couple (7, 0) and (7, 0)(1, 48) is a true answer, why? because it verifies the equation.</span>
