Step-by-step explanation:
Hullo :D
If you're having trouble understanding, you might not understand the Order of Operations.
P - Parenthesis. Solve what's inside the Parenthesis first
E - Exponents. Solve for Exponents second.
M - Multiply. Multiply numbers third. (left - to - right with division, too)
D - Divide. Divide fourth. It is interchangeable with multiplication, as well.
A - Addition. Add fifth.
S - Subtract sixth. It is interchangeable with Addition, as well.
With that in mind, all we need to do is identify these types in the equation:
(6+3)4
We see parenthesis. We will solve them first according to the Order of Operations:
6 + 3 = 9.
(9)4
We see multiplication. We solve them next according to the Order of Operations:
9 × 4 = 36.
Thus, the final answer is .
Hope this helps!
Answer:
(B)
Step-by-step explanation:
PRINCIPAL AMOUNT(p) = $400
RATE (r)= 250% = 2.5
INTEREST = $80
t = time (in days) = t/365
By using the formula,
r =
2.5 =
t =
t = 29.2
t = 29 days (approx)
Hence option (B) is correct.
