Answer:
Part a) 30+m
Part b) $36
Step-by-step explanation:
Part a) Identify an expression that represents the amount Susan spent on the fruits
The complete question in the attached figure
Let
m ------> the number of apples
n -----> the number of oranges
q ----> the amount Susan spent on the fruits
we know that
m+n=15 ----> (in total she needs 15 fruits)
n=15-m -----> equation A
q=3m+2n ----> equation B
Substitute equation A in equation B
q=3m+2(15-m)
q=3m+30-2m
q=30+m -----> expression that represents the amount Susan spent on the fruits
Part b) Identify the amount she spent if she bought 6 apples
we know that
If m=6 apples
substitute the value of m in the expression of Part a)
q=30+m -----> q=30+6=$36
