Help me please it urgent i have homework anyone there
Andru [333]

Answer:

14.9g + 9.5c

Step-by-step explanation:

g stands for $ earned training & c stands for $ earned working with customers

Anthony trained for 8.5 hours so, 8.5 hours x g $ earned at training = 8.5g

He worked with customers for 4.3 hours, so 4.3 hours x c $ earned with customers = 4.3c

Anthony's total $ earned is 8.5g + 4.3c

Madison trained for 6.4 hours so, 6.4 hours x g $ earned at training = 6.4g

She worked with customers for 5.2 hours, so 5.2 x c $ eared with customers = 5.2c

Madison's total $ earned is 6.4g + 5.2c

Anthony  8.5g  +  4.3c

Madison  6.4g  +  5.2c

If you add both their $ earned training, you get 14.9g

If you add both their $ earned with customers, you get 9.5c

To total what they both earn  it would be 14.9g + 9.5c
