Jonathan puts his life savings of $490 in a savings account that has an interest rate of 2.5% per year. If he does not take any money out over the next 7 years, how much will be in his account? Round to the nearest whole dollar.

568$

Step-by-step explanation:

a1(b)^n-1

First multiply the initial value (490) into 1.025 (Because it is growing so we add 1 to the rate converted into a decimal.) then n-1 or 7-1 which is 6, simply solve.

Its hard to explain so you should have an equation set up like this:

f(x)=490(1.025)^7-1

that is 568.249 (568)

Hope it helps.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
