You have the following equation for the cost of renting a car for x number of miles driven:
y = 0.15x + 65
If you travel 70 miles, then, x = 70 and you obtain for the cost y:
y = 0.15(70) + 65
y = 10.5 + 65
y = 75.5
Hence, the cost of renting a car to drive 70 miles is $75.5
Not sure if this is for algebra but this is the algebraic solution.
1. 5x + 1y = 25 (x meaning number of nickels) (y meaning number of pennies)
so 3 solutions could be, 5 nickels and 0 pennies, 4 nickels and 5 pennies, 3 nickels and 10 pennies.
2. First calculate how many days till the end of October, (31-14)= 17 days. then add 30 days for the entire month of November. Then add the 5 days that occurred in December. This will leave you with a total of 52 days.
Answer:
More Than
Step-by-step explanation:
According to the given statement:
This year the club earned $20 more than twice what it earned last year. Let x represent the amount raised last year.
The two words in this problem which tell us about the operation are "More Than"
This year club earned $20 more than than twice it earned last year. This means, to find the earnings of this year, double the earnings of previous year and add 20 to them.
Since, x represents the earnings of last year, we can represent the earnings of this year as:
Twice of x + 20
2x + 20
