Answer:
b, a, d (in that order)
Step-by-step explanation:
#1: since apples and bananas are each $0.40, to get the total cost, you would add the number of each and then multiply by 0.4.
#2. The ratio of heads of lettuce to guests should be the same. Therefore, [tex]\frac{37}{100} = \frac{x}{275}[/tex].
#3. We can distribute to get [tex]7x-4x+32 = 56[/tex], which simplifies to [tex]3x+32=56[/tex]
