(8, 11) is the correct solution. x = 8, y = 11
Plug it in:
11-8=3
That's correct.
N = -1/10rt + 1/10q
= −14n+q+4n=rt−4n+4n
= −10n+q=rt
= −10n+q+−q=rt+−q
= −10n=rt−q
= -10n/-10 = rt-q/-10
So the answer is:
= n = -1/10rt + 1/10q
Each snack cost $5.50
You start with $45, and afterwards end up with $12, so subtract 12 from 45 and you end up with 33. Then divide 33 by 6, since she bought 6 snacks, and you get $5.50.
Answer: 6 13/36 (B)
You add it by breaking wholes into parts.
The amount if $2950 is invested at an annual rate of 8.4% compounded quarterly is $3486
<h3>
Compound interest</h3>
Compound interest is given by:

where t is the period, r is the rate, P is the initial amount, A is the final amount and n is the times compounded.
Given P = 2950, r = 0.084, n = 4, t = 2, hence:

The amount if $2950 is invested at an annual rate of 8.4% compounded quarterly is $3486
