Ok so add .05 and .1 to get .15 so you have 7.10 left so divide by 5 because 3x is 3 and 2 more x's is 5x so divide 5 by 7.10 to get 1.42 so x is 1.42 so the drink is $1.52. that is the answer but just in case fries $1.42 and burger $4.31

All together: <span>3x + 0.05 + x + x + 0.10 = 7.50

5x + 0.15 = 7.50

5x = 7.35

x = 1.47

</span>1.47 +0.10=1.57<span>

so, the drink costs 1.57 </span>
