Question

You and friend purchase an equal number of magazines. your magazine costs 1.50 eachand your friends costs 2.00 each total cost for both is 10.50. solve equation

Answer 1

They both bought 3 magazines each. The total number of magazines bought are 6 magazines.

Answer 2

so we will use n= total number of magazines each

we start with $2n and $1.50n

then we add $2 and $1.50 = $3.50n

with that we put $3.50 into an equation $3.50n = $10.50

so now lets get rid of those decimals by taking 3.5 and doubling it to become 7 after that we need to double 10.5 to 21

so our new equation is 7n = 21

lets get n be itself by dividing 7 from both sides so that on the side with 7n the 7 cancels out

Finally n=21/7 which equals 3

so they both both 3 magazines each so if your looking for the total number of magazines between then they got 6 magazines
