Lesson 6: One-step equation word problems

# Modeling with one-step equations

Anna wants to throw a pizza party for her birthday. She has \$42.50 to spend on pizza boxes that cost \$8.50 each. To figure out how many pizzas she can buy, she divides the total money by the cost per box. This concept can also be applied to other situations, like a class selling candy boxes for a fundraiser.

• if this guy could just explain how to do it instead of all the extra i wouldnt be so confused.
• you dare insult this random guy's teaching abilities?
• What is a quotient?
• A quotient is the answer to a division problem!
• the video tutorial🥰😀
the actual work💀💀
• OMG!soooooooooo true!

• I still need help because i got a question its 10 less than j is 35.like what dose that supposed to mean?
• ★To model, (to write), the equation for…
"Ten less than j is 35"

Ten less than
means to subtract 10

Ten less than j
means to subtract 10 from j

j - 10 is 35
"is" means equals

so…
Ten less than j is 35
=
j - 10 = 35 ←equation made!

Needs to be with j isolated,
(to equal j)…

j - 10 = 35
=
j -10 +10 = 35 + 10
=
j = 35 + 10 ←equation = j
=
j = 45

(≧▽≦) I hope this helps!

• For the question 'Write an equation to represent the following statement.
The quotient of 36 and 3 is j.' I put 3 x _j_ = 36.
Then it said 'wrong. The answer is 36/3 = j."
Isn't that the same thing?
• While the equations are equivalent, it does not directly interpret the words. Quotient is divide, and you show no divide, verbs are generally =, and j is isolated on the right. You did not represent the statement, you changed the equation for some reason.
• i can,t do it crying right now
• I think you divide the total amount of money they have, by the number it costs for one.

ex. 100\$ and 2\$ per item.

(100/2=50 | 50 = # amount of items that can be bought)

• its very confusing its not helping with my problem!
• what is your problem exactly?
• yay i tottaly love this
