John invested the money at simple interest for 4.22 years.
We have,
Invested amount = $ 4500
Rate of interest = 5.5 %
Time = t years
Maturity value = $ 5545
So,
Total interest earned = $ 5545 - $ 4500 = $ 1045
And,
Simple interest = (Principal × Rate × Time ) / 100
So, Using the mentioned formula,
1045 = ( 4500 × 5.5 × t ) /100
1045 = 45 × 5.5 × t
⇒
t = (1045) / (45 × 5.5)
⇒ t = 4.22 years
Therefore, John invested the money at simple interest for 4.22 years.

y intercept goes after the slope:
Y= Mx + B
Y = -x + 3

sorry if it’s wrong
okay 1 student = 1/20 chance of picking yellow
1/20 (30/30) = 30/600 chance of picking yellow out of 30 studnets
30/600 = 0.05 = 5% chance of choosing yellow.
I each studnet picks 1 yellow marker. Is that all the options?
