Answer:
y = 550 when x = 2.5
Step-by-step explanation:
various ways to work this through: one simple way is to do cross method. arrange the numbers into fractions like this and then multiply the ones diagonal from each other
[tex]\frac{55}{0.25} =\frac{y}{2.5}[/tex]
then multiply 55*2.5 together. multiply 0.25 and y together. Now you have this:
137.5 = 0.25y
solve for y and you get y = 550
