a)Total number of fruit Brian bought in terms of x= 2x+3
b)Total money spent by Brian on the fruit= 0.9x+1.5
c)cost of each pear= (0.9x+1.5)/12
Step-by-step explanation:
As provided Brian got “x” apples and unknown quantity of oranges. However, amount of oranges bought was 3 more than apples
a). Hence the total number of fruit Brian bought in terms of x= no of apple +no of oranges
=x+x+3 (since he brought 3 oranges than apples. If apple is “x”, then oranges = “x+3”)
=2x+3
b). Total money spent by Brian on the fruit.
Total amount spent on apples= (cost of one apple* no of apples) + (cost of one orange * no of oranges)
Given Apples cost .40 and Oranges .50
=.4x+.5(x+3)
=0.9x+1.5
c). cost of 12 pears matches the total cost of the apples and oranges-
cost of each pear= total money spent on apples and oranges/no of pears bought
=(0.9x+1.5)/12
