The correct answer is Option 3: 12y
Step-by-step explanation:
A polynomial term is usually made of a variable and a co-efficient.
Like terms are those terms that have the same variables i.e. x and 44x are like terms.
Given expression is:
All the terms have only y which means that all three terms are alike.
The coefficients of like terms are added or subtracted according to their sign.
= 12y
Hence,
The correct answer is Option 3: 12y
Let's say she invested "a" amount at 7% and "b" amount at 9%
we know, whatever "a" and "b" are, they add up to 15000, thus
a + b = 15000
how much is 7% of a? well, (7/100) * a, or 0.07a
how much is 9% of b? well, (9/100) * b, or 0.09b
we know the sum of the interest for both is 1230, thus
0.07a + 0.09b = 1230
thus
solve for "a", to see how much was invested at 7%
what about "b"? well, b = 15000 - a
