Answer:
$5
Step-by-step explanation:
Let the cost of one burger be $b while the cost of one small fries be s
2 burgers and 2 small fries cost $14
This means that;
2b + 2s = 14
divide both sides by 2
b + s = 7 •••••••• (i)
Three burgers and four small fries cost $23
Mathematically;
3b + 4s = 23 •••••••• (ii)
From i , we can see that s = 7- b
we can now substitute this into equation ii
3b + 4(7-b) = 23
3b + 28 -4b = 23
4b -3b = 28 -23
b = $5
one burger costs $5
Number 1 is x=8!!
2 is pretty confusing so I hope someone else can answer two as I have answered 1!
Answer:
Leila is buying a dinosaur model. The price of the model is xxx dollars, and she also has to pay a 7\%7%7, percent tax.
Which of the following expressions could represent how much Leila pays in total for the model?
Step-by-step explanation:
The original price of the dinosaur model is "x" dollars
On top of that, the sales tax is 7% of the original price
Hence,
The total price would be the original amount PLUS the taxed amount
Original Amount = x
Taxed Amount = 7% of x
That is, 7% in decimal multiplied with "x".
7/100 = 0.07
0.07 * x = 0.07x
Total amount = x + 0.07x = 1.07x
The expression for total amount is 1.07x
