Answer:
<u>A) (1+0.3)25</u>
<u />
Explanation:
Zoe's expression <u>25+0.3(25)</u> equals to 32.5. So the only expression that equals to 32.5 is <u>A) (1+0.3)25</u>.
Add 4 to both sides to isolate the variable (-4+4=0) (2x+0=2x) (0+4=4) which leaves you with 2x=4 divide both sides by 2 to get rid of the number in front of the variable to get x by itself (2x/2=x) (4/2=2) therefore you’re left with x=2 (lo siento yo no hablo español la respuesta es x=2)
