how much does one apple cost?
how much does one banana cost?

Apple cost $1.00 while bananas cost $0.35

apples are $0.90 and bananas are $0.40

Step-by-step explanation:

3a+2b=$3.50

a+2b=$1.70

take the second equation and isolate one variable so it becomes a=$1.70-2b then you plug that into the a in the first equation

3($1.70-2b)+2b=$3.50

use the distributive property with the parenthesis

$5.1-6b+2b=$3.50

combine like terms

$5.1-4b=$3.50

subtract $5.1 from both sides

-4b=$-1.6

divide both sides by -4

b=$0.4

plug the $0.4 into the equation for b

3a+2($0.4)=$3.5

multiply the parenthesis

3a+$0.8=$3.5

subtract

3a=$2.7

divide

a=$0.9

x+y=90

x=30-y=x
