Answer:
c(n) = $1.25n - $0.50,
c(4) = $4.50
Step-by-step explanation:
if c = cost
and n = number of boxes
c = $1.25n - $0.50
You would divided both sides by 3 and 1x would equal 6
Since dividing by a fraction is multiplying by the reciprocal;
It's Keep Change Flip
So before you have:
15 divided by 9/2
we keep the 15
change the sign
and flip our fraction
so now we have
15 multiplied by 2/9
so now you can solve as normal
I believe when it's a fraction.
Answer:
510
Step-by-step explanation:
divide into chunks. I divided it like how you would draw the equal sign.
for top chunk, 20*8=160
for 2nd chunk, 8*25=200
for the last chunk, 15*10=150
add up 160, 200, and 150
