You need 70 bookmarks for a craft fair you begin with 35 bookmarks and make 10 bookmarks each hour. write an expression that represents the number of bookmarks you have after h hours

70 = 10x + 35 is your equation (10x + 35 is your expression).

3 1/2 hr is the time needed.

Step-by-step explanation:

Let hours = x.

You need 70 bookmarks, you have 35 (constant number), and you make 10 bookmarks an hour (varys).

Set the equation:

70 = 10x + 35

Solve for x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First subtract, then divide.

Subtract 35 from both sides:

70 (-35) = 10x + 35 (-35)

70 - 35 = 10x

35 = 10x

Isolate the variable (x). Divide 10 from both sides:

(35)/10 = (10x)/10

x = 35/10

x = 3.5

3 1/2 hours is your answer.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
