Question

To find an increase of 30% of price P, which expression should you use to find the final price?

A. .70p
B. .30p
C. 1.70p
D. 1.30p

Answer 1

The final price would be 1.3 times the original price P, or 1.3P. This corresponds to option D, 1.30P.

why the option D is correct

To find an increase of 30% of price P, you would need to use the expression:

D. 1.30P

This is because an increase of 30% means adding 30% of the original price P to P. Mathematically, this can be represented as:

P + 0.3P

Simplifying this expression, we get:

1.3P

Therefore, the final price would be 1.3 times the original price P, or 1.3P. This corresponds to option D, 1.30P.
