Joshua sells a pack of pens for $3.15, which is 5 percent more than he pays for them. which equation will find x, the amount he pays for a pack of pens? how many solutions will this equation have?
a.
x + 0.05x = 3.15, which has infinitely many solutions
b.
x + 0.5x = 3.15, which has one solution
c.
x + 0.05x = 3.15, which has one solution
d.
0.05x = 3.15, which has no solution

C.  

x + 0.05x = 3.15, which has one solution

Step-by-step explanation:

Let x = the price Joshua pays for the pack of pens

He add 5% (=.05 in decimal form)

That is x* .05

The new cost is 3.15

x+.05x = 3.15

This will have one solution

The correct option is C.

Step-by-step explanation:

It is given that Joshua sells a pack of pens for $3.15, which is 5 percent more than he pays for them.

Selling price of a pack of pens = $3.15

Let x be the amount he pays for a pack of pens.

x + 5% of x = 3.15

It can be written as

Divide both sides by 1.05.

The required equation is x+0.05x=3.15 and this equation has one solution.

Therefore, the correct option is C.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
