Dan invests £18790 into his bank account. He receives 4.9% per year simple interest. How much will Dan have after 3 years?

£21,552.13

Step-by-step explanation:

A = P(1 + rt)

P = £18790

r = 0.049 (rate in percent form)

t = 3 years

A = £18790(1 + (0.049)(3))

A = £18790(1 + 0.147)

A = £18790(1.147)

A = £21,552.13

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.
