Hello from MrBillDoesMath!
Answer: 5n - 2
where "n" is the number mentioned in the problem statement
Thank you,
MrB
Step-by-step explanation:
Step one:
given
current (older) fridge
electricity charges= $17 monthly
maintenance costs= $220
let the number of months be x
and the total cost be yo
the expression for the cost for the old fridge is
yo=220+17x---------1
New fridge
electricity charges= $6 monthly
costs= $1,050
let the number of months be x
and the total cost be yn
the expression for the cost for the old fridge is
yn= 1050+6x---------2
Hence the system of equation for the situation is
yo=220+17x---------1
yn= 1050+6x---------2
Step two
for 10 years there are 12*10= 120 months
put x= 120 in both expressions and compare the total
yo=220+17(120)---------1
yo=220+2040
yo=$2,260
yn= 1050+6(120)---------2
yn=1050+720
yn=$1770
<u><em>Based on the analysis it will be less expensive to get the new fridge, hence buying the new fridge is worth it.</em></u>
Answer:
a and e I believe
Step-by-step explanation:
this is because to answer those questions you need to survey multiple different people, you'd need more than just an answer if you were to find the average of something. For the other questions they're very direct and only have one answer. Therefore you wouldnt need a statistical process for the other questions and only for a and e.
