Brian invests ? 1900 into a savings account. the bank gives 3.5% compound interest for the first 2 years and 4.9% thereafter. how much will brian have after 6 years to the nearest pound?

let's check how much is it after 2 years firstly.

Brian invested the money for 6 years, so now let's check how much is that for the remaining 4 years.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

the answer is b
