Kipish [7]
<span>Eugene wants to buy jeans at a store that is giving $10 off everything.
Now, the tav on the jeans is marked 50% off and the original price is $49.98.
Let’s find the total cost if the 50% discount is applied before the $10 discount
Solutions:
=> 49.98 dollars * .50 = 24.99
Subtract this to get the answer:
=> 49.98 – 24.99 = 24.99 dollars, this is now that price of the jeans before 10 dollars discount is applied.</span>

a pound of chocolate costs 8 dollars. Felipe buys p pounds. write an equation to represent the total cost c that felipe pays
alisha [4.7K]

Answer:

c=8p

Step-by-step explanation:

So, we know that 1 pound of chocolate will cost $8. Felipe is going to buy "p" pounds of chocolate, and "p" means "any number"; so Felipe is going to buy any number of pounds of chocolate.

The formula we would use to calculate this is cost of one pound of chocolate multiplied by number of pounds of chocolate. And the way we can form this algebraically is by writing c=8p.

The "c" stands for total cost and we don't have to put the multiply sign when using algebra, as long as the figures are touching.
