You can put this solution on YOUR website! Martha and Sally had lunch together on Tuesday. Sally paid $2 more than Martha. If the total bill was $5.64, how much did Sally pay for her lunch?
a. $1.82
b. $2.00
c. $3.64 . $3.82
e. $7.64
:
Let the amount Martha Paid be:x
Then the amount Sally paid is:x+2 ($2 more than Martha)
Add the two and you get:$5.64
:
(x)+(x+2)=5.64
2x+2=5.64
2x+2-2=5.64-2
2x=3.64
2x/2=3.64/2
x=1.82
The amount that Martha paid is:x=$1.82
The amount that Sally paid is:x+2=1.82+2=$3.82 (d)
Happy Calculating!!!
