Sam places £3850 in a bank account that pays 1.3% simple interest per year. How much interest will she earn in 6 years?

she will earn 300.3 in interest

Step-by-step explanation:

using the formula for interest: I =Prt where P is the principal (starting amount), r is the rate, and t is the time. Always convert the rate to a decimal if it's in percentage form.

I = (3850)(0.013)(6)

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
