Blake needs a minimum of $145. He has saved $35 and plans to save $5.50 a week. About how many weeks will it take for Blake to s
ave enough money? a) at least 20 weeks; b) at most 20 weeks; c) at least 33 weeks; d) at most 33 weeks
1 answer:
Set up an equation.
35 + 5.50x = 145
Now, x is the amount of weeks, so we need to solve for that.
35 + 5.50x = 145
-35 -35
5.50x = 110
5.50x/5.50 = 110/5.50
x = 20
Answer: a) at least 20 weeks
