Answer:
10 hours
Step-by-step explanation:
320 = 30x + 20
300 = 30x
x = 10
4,000 if you set it up as unit rate with .15 on btm
We shall use the equation A = i(1 + r/n)^nt
So we shall plug all of that in so it turns out like this:
A = 4000(1 + 0.04/4)^4 x 7
So then that can be simplified to A = (1.01)^28
and then to A = 4000(1.321)
so then A = 5285.16

96,767,921

Step-by-step explanation:</h3>
5 - 7 + 2 - 6 ÷ 2 + 24^3 * 7000 - 76 = 96,767,921
Exponentiation is performed first, followed by multiplication and division in their order of appearance.
= 5 - 7 + 2 - 6 ÷ 2 + 13,824 · 7000 -76
= 5 - 7 + 2 - 3 + 96,768,000 -76
Then addition and subtraction are peformed in the order of appearance. (The commutative and associative laws apply.)
= (5 -7 +2) +96,768,000 -3 -76
= 96,767,921

A Google or Bing search box will evaluate an arithmetic expression strictly according to the order of operations. Your result is attached. The preferred symbols are * (asterisk) for "times" and / (slash) for "divided by". The usual ^ (caret) is used for "to the power of." If you intend grouping, parentheses are required.
