Answer:
9 small packs sold and 4 large packs sold
Step-by-step explanation:
Let's S be the number of small pack and L be the number of large pack. We have
S + L = 13 packs as the total number of hotdog packs
6S + 12L = 102 packs as the total number of hotdogs
We can divide both sides of the equation above by 6 then
S + 2L = 17
The subtract the S+L = 13 equation from this equation we get
S + 2L - S - L = 17 - 13 = 4
L = 4 packs
then S = 13 - 4 = 9 packs
So there were 9 small packs sold and 4 large packs sold

Answer:
$310
Step-by-step explanation:
The first step is to add the costs of the textbook together :
$68.41 + $105.35 + $72.49 + $59.91 = $306.16
In order to round off to the nearest ten dollars, look at the units figure, if the number is greater or equal to 5, add 1 to the ten figure. If this is not the case, add zero. Replace the unit digit with zero
The unit digit is greater than 6, so 1 is added to the tens digit. The amount becomes $310
