Answer:
The distance the Bensons had traveled from their home  hours after picking up their grand parents  292.5 miles
 hours after picking up their grand parents  292.5 miles 
Step-by-step explanation:
The given equation for the distance the Benson family traveled from their home can be presented as follows;
d = 55·t + 100
Where;
d = The total distance that the Benson family has traveled from their home after traveling 100 miles to pick up their grandparents 
t = The time duration the Benson family have been traveled from their grandparents home on the way to their vacation
To find how far from their home the Bensons will be after 3 1/2 hours of driving with their grand parents, we substitute t with 3 1/2 hours or 3.5 hours as follows;
d = 55·t + 100
When t =  hours, we get;
 hours, we get;

Therefore, the distance the Bensons had traveled from their home  hours after picking up their grand parents = 292.5 miles.
 hours after picking up their grand parents = 292.5 miles.

Answer:
$1.25f + $0.75f
Step-by-step explanation:
The cost of one bagel is $1.25 and cream cheese costs $0.75 per person. The total amount Jack and Jenn will spend on breakfast depends on the number of friends that eat breakfast.
to get the total amount spent on breakfast, multiply the cost of bagel by the number of friends and the cost of cream cheese by the number of friends. Add these numbers
The total amount spent on food = $1.25f + $0.75f
