Answer:
the answer is 73.5
Step-by-step explanation:
to find the are of the box you have to do the mathematical equation of LxWxH (lengthxwidthxheight) in this case L=6, W=3.5, and H=3.5 so your equation would be 6x3.5x3.5 = 73.5
Step-by-step explanation:
12 pounds cost $33.
so, 1 pound is ... ? well ?
it is $33/12 = $2.75
that means every pound he buys costs $2.75. no matter how many he buys, each and every pound costs these $2.75.

c = 2.75×m
Answer:
2 percent increase
Step-by-step explanation:
Let x be the first number
It increases by 70 %
The new number is
m = x+ .70x
= 1.7x
Let y be the second number
It decreases by 40 %
The new number is
n =y - .40 y
= .6y
The product of the original numbers is xy
The product of the new number is
mn = (1.7x * .6y) = 1.02xy
The new number is larger than the old number so it is an increase.
Percent increase is new - original divided by original times 100%
Percent increase = (1.02 xy - xy)
----------------- * 100%
xy
= .02 xy
------- * 100 %
xy
= .02 * 100 %
= 2%
