Answer:
b = $5
s = $6
Step-by-step explanation:
this can be solved using simultaneous equation 
s = streamers 
b = balloons
either of the 3 equations can be used to determine the price of the items
11b + 6s = 91 equation 1 
15b + 4s = 99 equation 2 
multiply equation 1 by 4 and equation 2 by 6
44b + 24s = 364 eqn 3 
90b + 24s = 594 eqn 4
subtract equation 3 from 4
230 = 46b
b = 5
substitute for b in eqn 1 
55 + 6s = 91
s = 6
