First, let’s break down the equation by combining like terms. You get 1a-4b, therefore making it answer choice b.
X = D/(1 - h)
1 - h = D/x
h = 1 - D/x
D = 400, X = 4000
h = 1 - 400/4000
h = 1 - 0.1 = 0.9
Answer:
The number of melon was 3 and the number of apples was 45.
Step-by-step explanation:
1. Melons cost $20 per crate and apples cost $8 per create. If the total was 48 crates for $420, you can make the following system of equations, where
is the number of melons and
is the number of apples:

2. By applying the Method of substitution, you can solve for
in the first equation and substitute it into the second one to find
. Then, you can substitute the value of
into the first equation to find
:
