A cup and saucer cost $3.10 at the local store. The cup costs $2.00 more than the saucer. How much does each cost?

Answer: cup is $2.55

Saucer $0.55

Step-by-step explanation:

Cost of cup and saucer is $3.10

Let the cup be x

And saucer be y

I. e

X+y = 3.10 ... equation 1

Cup which is X is $2 more than the saucer

I. e x=2+y ... equation 2

Substitute for X in equation 1

(2+y) + y=3.10

2+2y=3.10

2y=3.10-2

2y=1.10

Y=1.10/2

Y=$0.55

Substitute for y in equation 2

X=2+y

X=2+0.55

X=$2.55

Therefore

The cup is $2.55

The saucer is $0.55
