Three dogs (cosmo, fido, and max) have three different favorite toys
(ball, stick, doll).
• cosmo's favorite toy is a doll.

i think the answer is 12.67, if not then im not sure. the way i did it was replace all the x’s with 2 so youre left with:

2^3 + 2/3 + 2^3

so, from there you do the exponents 2*2*2 = 8 and 2*2 = 4

after that you do the division of 2/3 and youre left with the decimal 0.67

last step you add it all up to 12.67

hope it helps
