Solve the inequality shown here:

Nora set a goal to buy a new smart watch. She estimates the cost to be at least $350. She currently has $70 in savings. If she gets paid $40 per week to mow lawns, which inequality correctly represents the minimum number of weeks, w, that Nora has to mow in order to afford the smart watch?

• 70w + 40 ≥ 350

• 40w + 70 ≥ 350

• 70w + 40 ≤ 350

• 40w + 70 ≤ 350
