At the beginning of the week, James stopped by a local grocery store to buy fruit. He bought five bananas and three pears at a t
otal cost of $3.80. Later that week he went to the store again and bought another two bananas and four pears for $3.20. Assuming that prices did not change during the week, what was the price of one banana and one pear? haaaalllllp meh
Lets try to solve this problem using 2 equations, also,we will have bananas=b and pears =p
5b+3p= $3.80 2b+4p= $3.20 i will divide this equation by 2 and get b+2p= $ 1.60 we subtract 2p from both side so i can find the cost for 1 banana b+2p-2p=1.60-2p b= $1.60-2p
I will replace the b in the first equation now,
5(1.60-2p)+3p=$3.80 8-10p+3p=3.80 solving for p 8-7p=3.80 we subtract 8 from both sides -7p=-8+3.80 -7p=-4.20 we multiply both sides by (-1) 7p=4.20 we divide now both sides by 7 p=0.60 a pear cost 0.60 cents
