As per the problem
Amy and Mike going to an amusement park.
Admission for one person cost $18.
It mean total admission cost[tex] =2*18=36 [/tex]$
Ice cream cost $1 and 50 Cent.
It mean total ice cream cost[tex] =2*1.5=3 [/tex]$
Let Soda for two costs=$2x
Since total expenses[tex] =10+30.25=40.25 [/tex]$
Hence we can write
[tex] 36+3+2x=40.25\\
\\
\text{Take the like terms together and simplify we get}\\
\\
2x=40.25-39\\
\\
2x=1.25\\
\\
\text{Divide both the sides by 2 we get}\\
\\
x=0.625\\ [/tex]
Hence soda for one person cost $0.625
