Answer:
It will take her 14 months
Step-by-step explanation:
In this question, we are asked to calculate the number of months it will take kiera to increase her savings from 174 to 1350 if she adds a token of $84 to her savings each months.
Since we do not know the number of months, let’s represent this by m.
We model a linear equation to get m as follows;
Mathematically;
174 + 84(m) = 1350
Now we proceed to get m;
84m = 1350 - 174
84m = 1176
Thus, m = 1176/84 = 14 months
Answer: 14 months
Step-by-step explanation:
Current balance = $174
Amount added every month= $84
Proposed final balance= $1350
From the equation, the first term is 174 and common difference is 84.
The equation we will use is:
174 + 84x = 1350.
Collect like terms
84x = 1350 - 174
84x = 1176
Divide both side by the coefficient of which is 84
84x/84= 1176/84
X= 14
It will take 14 months for the money saved by Kiera to reach $1350.
