All together: 3x + 0.05 + x + x + 0.10 = 7.50 

 5x + 0.15 = 7.50 

5x = 7.35 

 x = 1.47 

1.47 +0.10=1.57

so, the drink costs 1.57 

Each drink costs $1.57

Based on the information given,the equation to solve the question will be:

3x + 0.05 + x + x + 0.10 = 7.50

Collect like terms

5x + 0.15 = 7.50

5x = 7.35

Divide both side by 5

5x/5 = 7.35/5

x = 1.47

Therefore, the cost of drink will be:

x + 0.10 = 1.47 + 0.10 = 1.57
