Unfortunality, he doesn’t have enough money, so he puts back 1 apple and 2

bananas.

b. Andrea’s budget is $6. If she buys equal number of apples and bananas, then

what is the maximum number of apples and bananas, she can buy?​

Answer 1

Step-by-step explanation:

5a+4b = 5.70 ---A

4a+2b = 3.60 ---B

2B-A =

3a= 7.2-5.7 =1.5

a = 1.5/3 =0.5

substitute value of a in B

2b=3.6-2 =1.6

b=0.8

a=0.5, b=0.8

b) 6= x(a+b)=x(.5+.8)

6 = x×1.3

x= 4.6

approx 4 apples, 4bananas
