Aplumber charges a customer a one time service fee of $79,$69 per hour for labor and a surcharge of $15 per hour due to the call being an emergency write an expression to represent the total charges for the plumber in two different ways

the two different ways that the total charges can be represented are

79 + 69x

79 + 84x

Step-by-step explanation:

Let x represent the number of hours that the Plumber is hired by the customer.

A plumber charges a customer a one time service fee of $79, then $69 per hour for labor and a surcharge of $15 per hour due to the call being an emergency. This means that

1) if the call was not an emergency, there would be no surcharge. Therefore, the total charge for x hours would be

79 + 69x

2) if the call was an emergency, there would be surcharge. Therefore, the total charge for x hours would be

79 + 69x + 15x

= 79 + 84x

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
