Answer: see Explanation
Step-by-step explanation:
THE GAINEY'S:
Recursive Formula :
A1 = $10
An = An-1 + $10
A2 = $10 + $10 = $20
Where n = day of the month
Explicit formula :
y = a + b(c - 1)
WHERE:
y = final amount
initial amount = a
Increment on initial amount = b
Day of the month = c
THE ARNOLD'S :
Recursive formula:
First day of the month (A1) = $10
An = 2(An-1)
A2 = 2(A1) = 2(10) = $20
A3 = 2(A2) = 2(20) =$40
Explicit formula:
y = a(b)^c
Where :
y = final amount
initial amount = a
Increment on initial amount = b
Day of the month = c
Answer:
-1
Step-by-step explanation:
6 cakes ... £2.40
10 cakes ... £x = ?
If you would like to know how much do 10 cakes cost, you can calculate this using the following steps:
6 * x = 10 * 2.40
6 * x = 24 /6
x = 24/6
x = £4
Result: 10 cakes cost £4.
