If you want to solve this problem using formulas, there are two important formulas:
t1 = first term = -5
tn = nth term = last term = -5
n = numbr of terms
Sn = sum of the n terms
tn = t1 + (n - 1)d ---> 65 = -5 + (n - 1)(5)
65 = -5 + 5n - 5
65 = -10 + 5n
75 = 5n
n = 15
Sn = n(t1 + tn)/2 ---> Sn = 15(-5 + 65)/2
Sn = 450
So ur answer rounds up to 450

Answer:
The profit is $16
Step-by-step explanation:
From the question, we have 20 kg at Birr y per kg
The cost price is thus;
20 * y = 20y Birr
Now for the selling price;
16 kg was sold at (y + 3/4) Birr per kg
we have here that;
16 * y + 3/4 * 16
= 16y + 12
The rest is thus; 20 - 16 = 4 kg
The rest of this at (y + 1) per kg will be
4 * (y + 1) = 4y + 4
The total selling price is thus;
4y + 4 + 16y + 12 = 20y + 16
The profit is the difference between the selling and cost price
We have this as:
20y + 16 - 20y
= $16
