Answer:
If we multiply two numbers together, we get a product. A product is the same as a multiple.
If we divide two numbers, we get a factor of the number we are dividing. A factor is the same as a divisor.
Knowing this, we can create two equations.
pq = 210 eq1
p/q = 14 eq2
We have a system of equations. If we substitute eq2 into eq1 so the eq1 is in terms of eq1, we obtain
(14q)q = 210
14q2 = 210
Solve for q from this equation.
q2 = 15
Square-root both sides of the equation.
q = √15

Answer:-
I think it’s Quadratic, since as in a quadratic equation:
ax^2 + bx + c = 0
So, let's say the soft drink equals y and the sandwich equals x.
x + y = 9.9
The sandwich costs 3.5 times as much as the soft drink
x = 3.5y
Therefore, we can replace x with 3.5y since they're the same thing
3.5y + y = 9.9 <-- That's the equation :)
