Question

Leila is buying a dinosaur model. The price of the model is
\[x\] dollars, and she also has to pay a
\[7\%\] tax.
Which of the following expressions could represent how much Leila pays in total for the model?
Choose 2 answers:
A

\[\dfrac{107}{100}x\]
B
\[0.7x+x\]
C
\[1.07x\]
D

\[x+\dfrac{7}{10}x\]
E
\[1.7x\]

Answer 1

7% = 7/100 = 0.07, so total = x + 0.07x = 1.07x.
That matches A (107/100 x) and C (1.07x).
