2)$3.44

Step-by-step explanation:

4 cans and 3 loaves=11.67

8 cans and 1 loaf= 12.89.

Set up equation:

x=cans

y=loaves

$4x+3y=11.67\\8x+y=12.89$ This is the answer for question A.

Multiply eq1 by 2:

$8x+6y=23.34$

Subtract eq3 by eq2:

$5y=10.45\\y=2.09$

Substitute:

$8x+2.09=12.89\\8x=10.8\\x=1.35$

One can of soup and one loaf of bread=

$1.35+2.09 or 3.44$

So:

$$3.44$

Hope this helps :D Please hit the crown if u can !!
