(b) 1800. 600n - 12000, n. 17
(0) 1800n + 600 - 12000, n6
(d) 1800n 600 12000, n.7
Answers
Answer:
option b is correct that us 1800+600n=12000; n=17
Explanation :
ankita has - 1800 already
save- 600 each week
she wants a new guitar that is costiong - $12000
∴ equation will be : 1800 + 600n = 12000
= 1800 + 600n = 12000
= 600n = 12000 - 1800 that is 600n= 10200
= n = 10200 ÷ 600
= n = 17

Given : Anita has Rs 1800 and she saves Rs 600 each week to buy a new guitar that costs Rs 12000.
n represents the number of weeks that she saves money to have the required amount,
To Find : Equation that represents the situation
the value of n
Solution:
Savings available = 1800 Rs
Saving per week = 600 Rs
Number of weeks = n
Saving in n weeks = 600n Rs
Total Saving = 1800 + 600n Rs
Saving required = 12000 Rs
Equate both
=> 1800 + 600n = 12000
=> 3 + n = 20
=> n = 20 - 3
=> n = 17
Hence 17 weeks
value of n = 17
