Answer:
Solve always tries to give you explicit formulas for the solutions to equations. However, it is a basic mathematical result that, for sufficiently complicated equations, explicit algebraic formulas in terms of radicals cannot be given. If you have an algebraic equation in one variable, and the highest power of the variable is at most four, then the Wolfram Language can always give you formulas for the solutions. However, if the highest power is five or more, it may be mathematically impossible to give explicit algebraic formulas for all the solutions.

Answer:
52%
Step-by-step explanation:
We are told that, of all customers 65% buy a burger. This would imply that the proportion of customers who buy a burger is 0.65.
Moreover, if a customer buys a burger, the probability they buy french fries is 0.80. This implies that the proportion of customers who buy fries given that they bought a burger is 0.8.
Therefore, the proportion of customers who get a burger and fries is simply the product of the two probabilities;
= 0.65*0.8
= 0.52
Therefore, 52% of all customers get a burger and fries
