You’re right, both of the pairs are similar
The constant of proportionality (k) equals the total price (y) divided by the number of cans (x).
Step-by-step explanation:
Answer:
Abel is 3 years older than Zoe.
Step-by-step explanation:
Abel: y = 1266.77(1.03)^t
Zöe: y = 1159.27(1.03)^t
To find the difference in children's ages first we take ratio of 1266.77/1159.26
Ratio of 1266.77/1159.26= 1.09
now when you write ratio in terms of powers of 1.03
1.03^t = 1.09
Take ln on both sides
t ln(1.03) = ln(1.09)
Then you divide both sides by ln(1.03)
t= 3
Abel is 3 years older than Zöe.
