n=3

Step-by-step explanation:

step 1- subtract 3 to both sides

+3-3=0    18-3=15

5n=15

step 2- divide both sides by 5

5÷5=1       15÷5=3

step 3- check answer by plugging in for n

5(3)+3=18

15+3=18

18=18

firts lets see how many dollars she has

192 divided by 4 is 48 so she currently has 48 dollars.

and she puts in 2 quarters daily

so lets see how much she need to earn

75 - 48 is 27

lets see how many quarters she need to have 27 dollars 27 x 4 is 180

now lets divide 180 by two because shes giving two everyday. 180 divided by 2 is 54 so if she kept adding two quarters everyday it would take her 54 days to get the rest of the money she need to by and iPod.


i dont know if this helped or not but i solved it
