Question

Zoe compares the price of a sweatshirt at two stores. At Store A, the sweatshirt costs $25. A friend told her that the sweatshirt costs 30% more at Store B.
Zoe wrote the expression 25+0.3(25) to find the price of the sweatshirt at Store B.Which equivalent expression could she also use to find the price of the sweatshirt at Store B?

25 + 0.3

(1+0.3)25

(1−0.3)25

1+0.3(25)

Answer 1

Its the second one. With (1+0.3)25 multiply 25 by 1 and then multiply 25 by 0.3 and add both answers. With 25+0.3(25) you still multiply 25 by 0.3 and you add 25.
