10 small and 8 large cost $192. 20 small and 1 large cost $99. What is cost of a small
2 answers:
Answer:
Step-by-step explanation:
small=s, s=3.99
large=l, l=19.20
10s+8l=192.20
20s+l=99
we can see that in the second equation, 20s+l=99
l=99-20s
lets replace l in the first equation
10s+8(99-20s)=192.20
10s+792-160s=192.20
-150s=-792+192.20
150s=599.80
s=3.99
l=99-20(3.99)=99-79.80=19.20
Answer:
19
Step-by-step explanation:
You can set up a system of equations.
x=small, and y = large.
10x+8y=$192
20x+1y=$99
you can multiply the first equation by -2 to get rid of x:
20x+1y=$99
-20x-16y=-$384
when you combine them, you get:
-15y=$-285
you can divide by -15 and you get:
y=19, so 1 large equals $19

Step-by-step explanation:
Start with our equation:
s=2(lw+wh+hl)
Plug in our values for l, w, and h:
s=2(12*9+9*2+2*12)
Simplify:
s=300
