Melons cost $20 pet Crate, and apples cost $8 per create. an order comes in for a total of 48 crates for $420. what was the numb

Alika [10]

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 $x$ is the number of melons and $y$ is the number of apples:

$\left \{ {{x+y=48} \atop {20x+8y=420}} \right.$

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

$y=48-x$
