Erik is an RN at the hospital. He gets a standard rate of pay for 40 hours. He gets 175% of that rate for overtime. One week Erik works his regular 40 hours and has 16 hours of overtime. He makes $680 that week. Which equation would solve for the standard rate of pay? A. 40r + 16 (1.75r) = $680 B. 40r + 16 (0.75r) = $680 O C. 40r + 16 (1.75 +r) = $680 D. 40r + 16 (175r) = $680 E. 40r + 16 ( 175 ) = $680​
