Sometimes all you need is good friends, new friends, beer and Christmas cheer.
Thank you God for answering some prayers
Yesterday I spent my time reviewing percentage problems and simultaneous equations.
And also word problems aka fill in the blank with correct vocab word.
Examples of a Percentage problem
"A hardware store is selling a lawnmower for $300. If the store makes 25% profit on the sale, what is the store’s cost for the lawnmower?"
Have your answer? Go ahead and check below to see how well you did.
Solved this way:
The selling price of $300 represents 100% of the store’s cost plus 25%of the store’s cost. Use .25 x Cost to represent the profit in an equation; solve the cost.
selling price = Cost + Profit
selling price = 1 x Cost + .25 x Cost
$300 = 1 x Cost + .25 x Cost
$300 = 1.25 x Cost
$300/1.25 = Cost
$240 = Cost
