Answer:

y=10

Step-by-step explanation:

$\frac{4}{100}$ = $\frac{y}{250}$

cross-multiply, 4*250=100y

isolate the variable and solve for y, 1000=100y

divide 100 on both sides, 10=y

A taxi cab charges $1.50 for the flat fee and $0.50 for each mile. Write an inequality to determine how many miles Sharon can tr

Korvikt [17]

Answer:

C. $0.50x+1.50\leq 25$

Step-by-step explanation:

Let x represent number of miles.

We have been given that a taxi cab charges $1.50 for the flat fee and $0.50 for each mile.

The cost of riding x miles would be $0.50x$ and the total cost of riding x miles would be $0.50x+1.50$ .

Since Sharon has only $25 to spend on the taxi ride, so the cost of riding x miles on taxi must be less than or equal to 25.

We can represent this information in an inequality as:

$0.50x+1.50\leq 25$

Therefore, option C is the correct choice.
