Leigh-Anne invests £2500 for 4 years in a savings account. She gets 3% per annum compound interest.
How much money does Leigh-Anne have at the end of 4 years.

After 4 years, Leigh-Anne will have £ 2,813.77 in her account.

Step-by-step explanation:

Given that Leigh-Anne invests £ 2500 for 4 years in a savings account, and she gets 3% per annum compound interest, to determine how much money does Leigh-Anne have at the end of 4 years, the following calculation must be performed:

X = 2,500 x (1 + 0.03 / 1) ^ 4

X = (2,500 x 1,003) ^ 4

X = 2,813.77

Thus, after 4 years, Leigh-Anne will have £ 2,813.77 in her account.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20
