Hi, i'm stuck on some questions that i need answered.
I have 3 questions i need help with.
I'm not sure where to start in order to answer the question.
I also have to show working.
What is a% of b% of c% of 1000 000?
Solve for x and y:
2x - 3y = 8 ....................(1)
5x + 2y = 31.4 ...............(2)
a) The store orders twice as many four burner BBQ’s as six burner BBQ’s. Each four burner BBQ is priced at $299 whilst each six burner BBQ is $450. The total bill for the order is $14 824 which includes a freight charge of $1 200.
Use algebra to determine the number of four burner and six burner BBQ’s ordered.
Let x = total of four burners, y = total of six burners
$14 824 = (x*299)+(y*450)+1200
$13 624 = (x*299)+(y*450)
$13 624 = 299x + 450y
