The expression to represent the cost, in dollars, for 5 people to go horseback riding for 2 hours each is $ (15 + 10x)
Solution:
Given that The total cost to go horseback riding is "x" dollars per hour plus a $3 fee for renting a helmet.
total cost = $ 3 + "x" dollars per hour
To find: expression to represent the cost, in dollars, for 5 people to go horseback riding for 2 hours each.
Let us first find the total cost for 1 person to horse ride for 2 hours
total cost for 1 person = $ 3 + 2x
Thus to find total cost for 5 people to go horseback riding for 2 hours each is found by multiplying the above expression by 5
Total cost for 5 people = 5 x total cost for 1 person
[tex]\text{ Total cost for 5 people } = 5 \times (3 + 2x)[/tex]
[tex]\text{ Total cost for 5 people } = 15 + 10x[/tex]
Thus the expression to represent the cost, in dollars, for 5 people to go horseback riding for 2 hours each is $ (15 + 10x)
