Answer:
12s +3j= 85.95
15s +2j= 93.55
Step-by-step explanation:
First, define the variables:
Let the cost of a shirt be $s and the cost of a pair of jeans be $j.
From the first sentence:
12s +3j= 85.95 -----(1)
From the second sentence:
15s +2j= 93.55 -----(2)
There's no if about it,
has a zero
so
is a factor. That's the special case of the Remainder Theorem; since
we'll get a remainder of zero when we divide
by
At this point we can just divide or we can try more little numbers in the function. It doesn't take too long to discover
too, so
is a factor too by the remainder theorem. I can find the third zero as well; but let's say that's out of range for most folks.
So far we have
where
is the zero we haven't guessed yet. Again we could divide
by
but just looking at the constant term we must have
so
We check
We usually talk about the zeros of a function and the roots of an equation; here we have a function
whose zeros are
