As a scuba diver descends into deeper water, the pressure of the water on the divers body steadily increases. The total pressure on the diver is the sum of the pressure from the atmosphere and the pressure from the water. Use the information in the graphic to find the depth at which a diver
SCUBA DIVING Problem A SOLUTION Solve a multi-step problem STEP 1 Write a verbal model. Then write an equation. = P + =
2117 + 64 d STEP 2 Find the depth at which the pressure is 8517 pounds per square foot. P = 2117 + 64d
8517 = 2117 + 64d -2117 ANSWER -2117 6400 64d = 64 64 100 = d Write equation. Substitute 8517 for P. Subtract 2117 from each side.
Simplify. Divide each side by 64. Simplify. A diver experiences a pressure of 8517 pounds per square foot at a depth of 100 feet. Problem B JOBS Kim has a job where she makes $8 per hour plus tips. Yesterday, Kim made $53, including $13 from tips. How many hours did she work? JOBS
