Sofía has $345 in her bank account, she saves $25 every week. Write an equation for the total amount in her bank account T after w weeks.

• $T=25w-345$

• $T=345w+25$

• $T=25w+345$

• $w=25T+345$

Use x and y as variables and write an equation to model the situation. The total cost of gas y is the number of gallons x times $2.25

• x = 2.25y
