Printer ink cartridges cost $19 each. The company that sells the ink cartridges charges a flat shipping rate of $7.50, no matter how many ink cartridges you buy.
Write an algebraic expression that describes the total cost for a single order of x, cartridges
The algebraic expression that describes the total cost for a single order of x cartridges would be:
Total cost = (19 * x) + 7.50
To write an algebraic expression that describes the total cost for a single order of x cartridges, we can add the cost of the cartridges to the flat shipping rate.
The cost of x cartridges at $19 each can be represented as 19x.
The flat shipping rate is $7.50, which remains constant regardless of the number of cartridges ordered.
Therefore, the algebraic expression for the total cost of x cartridges would be:
19x + 7.50
To find the total cost for a single order of x ink cartridges, you need to consider the cost of the ink cartridges and the flat shipping rate.
The cost of x ink cartridges can be calculated by multiplying the cost per cartridge ($19) by the number of cartridges (x). This expression can be written as 19x.
The flat shipping rate is $7.50, which is not dependent on the number of cartridges. Hence, we can simply add this flat rate to the cost of the ink cartridges.
The algebraic expression that describes the total cost for a single order of x cartridges is:
Total Cost = 19x + 7.50
