Question

@ajaylounsber Jennifer has been saving for college for 57 months. The first month, she saved $11. She was able to save more money each month than the month before. She ended up saving $19,779.00. How much more did she save each month?,

Answer 1

Jennifer has been saving $12 more each month. If she started saving $11 each month, the next month she would have to save $23. The third month she would save $35 and so on and so forth if she ended up saving 19779 by the end of the 57 months. When you multiply 11 by 57 months, you find that number and subtract it by the total which is 19779. This would bring you at 19152. Divide that by 1596 which we got using the derivation formula (s = n/2) and you would get $12 more saved up each month.
