Question

Britney paid $4.50 for two mangoes and one bag of grapes. Finn paid $9.25 for three mangoes and two bags of grapes. Britney and Finn both paid $1.25 for each mango. How much more did Finn pay for a bag of grapes? Plz help asap!

Answer 1

b. 4.5=2m+g
f. 9.25=3m+2g

1.25=m

sub

b. 4.5=2(1.25)+g
f. 9.25=3(1.25)+2g

b. 4.5=2.5+g
f. 9.25=3.75+2g

minus 2.5 from both sides on the b. equaion and minus 3.75 from both sides on the f. equation

b. 2=g
f. 5.5=2g

divide both sides of f. equation by 2

b. 2=g
f. 2.75=g

2.75-2=0.75
finn paied $0.75 more for a bag of grapes
