Please help fast

Answer 1

Each eraser would be 85 cents. 
You subtract $7.30-$3.00=4.30
so then you subtract $4.30-$1.75 which gives you $2.55
your last step is to divide so $2.55 dived by 3 because you bought 3 erasers

Answer 2

3.00+1.75=4.75 7.30-4.75=2.55 2.55/3=0.85 Sophia spent $0.85 on each eraser.
