Answers
Explanation :
Ankita has - 1800 already
save- 600 each week
let the no. of weeks be - x
she wants a new guitar that is costiong - $12000
∴ equation will be : 1800 + 600x = 12000
= 1800 + 600x = 12000
= 600n = 12000 - 1800 that is 600x= 10200
= x = 10200 ÷ 600
= x = 17

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