The total cost to go horseback riding is x dollars per hour plus a $3 fee for renting a helmet. write an expression to represent the cost, in dollars, for 5 people to go horseback riding for 2 hours each.

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

Thus the expression to represent the cost, in dollars, for 5 people to go horseback riding for 2 hours each is $ (15 + 10x)

a = 11 : 4

b = 38

c = 1 for every 6

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
