Justin Bieber had $815 in his savings account. He wants to keep at least $150 in the account
at all times. He withdrawals $35 each week for music. Write and solve an inequality to
show how many weeks he can make withdrawals from the account.
Please help it is urgent!!

Let x = number of weeks.

815 - 35x ≥ 150.

Subtract 815 from each side

-35x ≥ -665

Divide each side by -35

x ≤ 19

He can withdraw $35 every week for at most 19 weeks.

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
