Question

The price of a skateboard is 5 dollars less than 3 times the price of a pair of knee pads. Let k represent the price of the knee pads. Write an expression that gives the price of the skateboard

Answer 1

Answer:

Price of skateboard= $3k-5$

Step-by-step explanation:

Given: The price of a skateboard is 5 dollars less than 3 times the price of a pair of knee pads.

Lets assume the price of the knee pads be "k".

As given, The price of a skateboard is 5 dollars less than 3 times the price of a pair of knee pads.

∴ y-intercept is 5 and slope will be 3.

using y intercept expression to form an expression.

we know, $y= mx+b$

∴ Price of skateboard= 3\times k-5

Price of skateboard= $3k-5$

Hence, expression for price of skateboard is $3k-5$
