Answer:
 a taco is 1.25 and a drink is 0.95
Step-by-step explanation:
tacos = t
drinks = d
5t + 3d = 9.10
3t + d = 4.70
this is a simultaneous equation so times the first one by one and the second by 3 and then take them away from each other and solving to get
t = 1.25 and d=0.95
one drink is $0.95
one taco is $1.25
Hope this helps!!
