Answer:

The answer is that Topsoil costs 10$ more than mulch.

When we look at the equation y=20x, we see that for one cubic yard, it costs 20$. when we look at the graph, we see that for one cubic yard it costs 30$ for topsoil, therefore, Topsoil is $10 more than mulch for each cubic yard.

9x-2y=-21 2x+3y=16 Substitution

hjlf

$9x-2y=-21 \\\\ 9x=-21+2y \\\\ => \boxed{x=\frac{2y-21}{9}} \\\\ 2x+3y=16 \\\\ 2*\frac{2y-21}{9}+3y^{(9}=16^{(9} \\\\ 2(2y-21)+27y=144 \\\\ 4y-42+27y=144 \\\\ 31y=144+42 \\\\ 31y=186 \\\\ \boxed{y=\frac{186}{31}=6} \\\\ x=\frac{2*6-21}{9} \\\\ x=\frac{12-21}{9} \\\\ x=\frac{-9}{9} \\\\ \boxed{x=-1}$

the school store has1200 pendls in stock and sells and sells an average of 25 pencils per day the manager reorders when the numb

forsale [732]

Answer:

Number of pencils in stock = 1200

Average number of pencils sold by the manager per day = 24

Number of pencils that would be sold before reordering = 1200 - 500

= 700

Then

The number of days after which the manager will reorder = 700/24

= 29.16

So the manager has to reorder after about 30 days. Since the answer comes in fraction of more than 29 days, so it has to be 30 days. I hope the procedure is clear for your understanding.

Just to be clear, this answer is not mine, but I remember seeing this question so I just copied someones' answer. Still, you might find this helpful.
