Question

Brian bought x apples and some oranges. Brian bought 3 more oranges than apples.

Answer 1

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
