Answer:
$28.8
Step-by-step explanation:
First we need to get the interest on the savings for the 4years. Since it is not compounded, we will use the simple interest (SI) formula.
According to the simple interest formula, SI = Principal × Rate × Time/100
Give principal = $24 rate = 5℅ time = 4years
SI = 24×5×4/100
SI = 480/100
SI = $4.8
Zoe interest for four years will be $4.8.
Amount she has saved for 4years = principal + interest = $24+$4.8
= $28.8
Answer:
y = 6 when x = 18
Step-by-step explanation:
The appropriate formula for this direct proportion is y = kx, where k is the constant of proportionality.
We know y = 3 when x = 9: 3 = k(9)
This yields k = 3/9, or k = 1/3
Then the formula is y = (1/3)x
and when x = 18, y = (1/3)(18) = 6
y = 6 when x = 18
