Exercise 1 Page 147

Assume the number of weeks is x, and construct an equation that represents the number of weeks he needs before reaching his goal.

30 weeks

Practice makes perfect
Let's call the number of weeks Orlando needs to reach his goal x. He already has $1350 in his account, and he is planning to deposit $40 each week. If his goal is to increase the balance to $2550, we can write the following equation. 1350+40x=2550 Let's solve the equation by isolating x.
1350+40x=2550
40x=1200
x=30
He needs 30 weeks to reach his goal.
