How do you write this in an algebraic expression?
1. jenny had $130, but she is spending $10 per week.
2. the piggy bank contained $25, and $1.50 is added each day.
3. you had 250 minutes left on your cell phone, and you talk an hour a week.
you very much if you can answer all !

1. Since Jenny had $130, but she spends $10 per week, then the amount that she has left every week will be:

= $130 - (10 × w)

where,

w = number of weeks

= $130 - (10 × w)

2. Since the piggy bank contained $25, and $1.50 is added each day, the algebraic expression will be:

= $25 + (1.50 × d)

= $25 + 1.5d

where, d = number of days.

3. You had 250 minutes left on your cell phone, and you talk an hour a week, the algebraic expression will be:

= 250 - (60 × w)

= 250 - 60w

where, w = number of weeks

Note that 60minutes = 1 hour
