Answer:
the first one (25x + 30y is less than or equal to 100)
Step-by-step explanation:
money for clothing set x amount of sets plus pairs of shoes has to be less than or equal to 100 dollars.
X=alice
b=barry
c=charlene
x=15 more than b
x=15+b
c=2 times of b
c=2b
all together
x+c+b
15+b+2b+b
15+4b
they have 15+4b or 15+4 times of barry
if we want in terms of x
x=15+b
x-15=b
15+4(b)
15+4(x-15)
15+4x-60
4x-45
they have 4x-45 together
