Suppose you start with at least $52 in your savings account and deposit $27 each week. Write an inequality to describe how much money m you have after w weeks. If you do this for 11 weeks, will you have enough to buy a bicycle that costs $340? Show your work.
Hi Gamemasterx40,
Suppose you start with at least $52 in your savings account and deposit $27 each week. Write an inequality to describe how much money m you have after w weeks. If you do this for 11 weeks, will you have enough to buy a bicycle that costs $340? Show your work.
52, 52+27, 52+27*2, .............. 52+27w
After w weeks I will have 52+27w dollars
After 11 weeks this equals
52+27*11 = 349
which is enough to buy the bike that I want.
Mmm in 3 months I can have that bike

You can use greater than or equal as an inequality since there can be tax or bonus (Depends very much, could be an equality aswell)
m (total) >/= 52 (start value) + 27 . w (weekly deposit)
So, taking 11 as time, you can use
M >/= 52 + 27*11
M >/= 52 + 297
M >/= 349
If the bike costs you 340, and obviously 349 > 340
Yes, you can buy one
