Worked example
Ava is tracking a savings account growing by a fixed amount each week. After 13 weeks, the total is $894.40
The account starts at $0, with no interest, fees or withdrawals
What is the amount saved for 11 weeks? Give your answer in dollars, to the nearest cent
Find dollars saved per week
\[\$894.40 \div 13 = \$68.80\text{ per week}\]Multiply dollars saved per week by the new number of weeks
\[\left(\$894.40 \div 13\right) \times 11 = \$756.80\]The answer is $756.80
