Answer:
$11.10
Step-by-step explanation:
1 small package = $2.40
1 large package = $2.90
1 small package + 3 large packages.
2.40 + (3 × 2.90)
=2.40 + 8.70
=11.1
This problem can be modeled by 2.4x+2.9y=c
x=small packages
y=large packages
c=total cost
By plugging in the values you get 2.4(1)+2.9(3)=c
2.4+8.7=c
c=11.1
Therefore the total cost is $11.10
