Answer:
I = 60 + 18k
Step-by-step explanation:
Data provided in the question:
The function for number of loaves, N that Moses bake
⇒ N(k) = 10 + 3k
here,
k is the kilograms of floor received
and,
Income in dollars, I(x) = 6x
here, x is the number of loaves baked
thus,
when k kilograms of flour is received,
x = N(k) = 10 + 3k
substituting x in income function,
we get
I = 6(10 + 3k)
or
I = 60 + 18k
A = 2
b = 0
2a + 2b = 4 → 4a + 4b = 8
(4a + 4b = 8) - (4a - 3b = 8) → 7b = 0
b = 0
so a = 2

Answer:
The cost of an adult ticket is $12.50
Step-by-step explanation:
The given information are;
The cost of two adult tickets and three children tickets = $43.00
The cost of one adult ticket and one child ticket = $18.50
Whereby the cost of an adult ticket is represented by <em>x</em> and the cost of a child's ticket is represented by <em>y</em>, we get the following two simultaneous equations;
2·x + 3·y = 43.00...(1)
x + y = 18.5...(2)
(ii) Multiplying equation (2) by 2 and subtracting the result from equation (1) gives;
2·x + 3·y - 2×(x + y) = 43 - 2×18.5 = 6
2·x - 2·x + 3·y - 2·y = 0 + y = 6
∴ y = 6
The cost of each the children ticket = $6.00
From equation (2), where y = 6, we get;
x + y = 18.5
∴ x + 6 = 18.5
x = 18.5 - 6 = 12.5
The cost of an adult ticket, x = $12.50.
