Margarito opened a savings account with a $500 deposit and a simple interest rate of 5.6%. if there were no deposits or withdrawals, how much total money is in the account after 8 ½ years ?

Hey there!

Simple interest is based on only the original deposit of money, which in this case is $500.

To find 5.6% of 500, we can multiply it by the decimal that represents that part of a whole: 0.056.

The question asks for how much money is in the account after 8 1/2 years. This means we multiply the interest for 1 year (28) by 8 1/2.

Lastly, we add the interest to the original deposit.

The answer is $738.

Hope this helps!

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
