Write and solve an equation to represent the given situation. be sure to define your variable.
samantha currently has $1500 in the bank and is spending $35 per week. how many weeks will it take until her account is worthy only $915?

17 weeks

Step-by-step explanation:

Let x= Number of week.

y= balance amount in account

Given :  Samantha currently has $1500 in the bank and is spending $35 per week.

Rate of spending =  $35 per week

Spending in x weeks = $35x

As per the given statement , the required equation will be :-

Balance Amount = Current amount - Rate of spending x Number of week

For y= 915, we have

Subtract 915 from both sides and 35x to both the sides , we get

Hence, it will take 17 weeks until her account is worthy only $915.

b) 1/3 * 1/5
