Question

You save $35 each week. You now have $140. You plan to save enough money for a cruise that costs $1,050. Write and solve an equation to find the number of weeks it will take to save for the cruise.​

Answer 1

It will 26 weeks to save for the cruise starting from a balance of $140

(It will take 30 weeks in total, if you start saving from $0)

Explanation:

let x = number of weeks

Given starting balance = $140

⇒ 140 + 35x = 1050

⇒ 35x = 1050 - 140

⇒ 35x = 910

⇒ x = 910 ÷ 35

⇒ x = 26
