Lincoln is saving $360 to buy a new bike. he already has $85 and can earn $12 per hour at work. which of the following equation describes the number of hours, h, for which Lincoln must work to earn enough money to buy the new bike?

Answer: Lincoln needs to work for 23hrs to have enough money to buy a new bike

Step-by-step expression

Lincoln is saving $360

He has $85

He can earn $12hr

Step 1: Make an Equation

12h + 85 = 360

Step 2: Solve for h

12h + 85 = 360

-subtract 85 on both sides

12h = 275

-divide 12 on both sides

h = 22.91

h ≈ 23

Step 3: Check your work

12h + 85 = 360

12 (23) + 85 = 360

276 + 85 = 360

361 ≈ 360
