Answer:
$28.3
Step-by-step explanation:
x=rate for 1km
y=initial fee
Mike: $35 for 15km -> 35 = 15x + y
Thomas: $24.50 for 10km -> 24.50 = 10x + y
Using those two equations we see the following:
Mike paid $10.5 more for 5 more km. The initial fee remains unchanged, so we can calculate the rate for 1km, which is 10.5/5=2.1.
35 = 15x + y
24.50 = 10x + y
10.5 = 5x
2.1=x
Using that value with one of the original equations we can calculate the initial fee.
35 = 15x + y
35 = 15*2.1 + y
35 = 31.5 + y
3.5 = y
Mike paid 15*2.1=31.5 ($2.1 for every km) plus the initial fee, his total was $35.
We subtract the 31.5 from the 35(total) and get the initial fee, which is $3.5.
<u>Let's see what Lex will pay:</u>
Km travelled times 2.1 (the rate for 1km) plus 3.5 (the initial fee).
12*2.1 + 3.5 = 28.3
Lex will pay $28.3 for the same taxi company to travel 12 km.
Answer:
1 and 0
Step-by-step explanation:
they tell us what hundred and that it IS a hundred
To make a fraction a percent, you have to divide the numerator by the denominator. You get a decimal. Multiply the decimal by 100 to get the percent or just move the decimal two places to the right.
So,
1.
Divide 1 by 5 and you get 0.20
Multiply 0.20 by 100. The answer is 20%
2.
Divide 2 by 3 and you get 0.6666.......
Multiply 0.6666..... by 100 and you get 66.6%
3.
Divide 1 by 40 and you get 0.025.
Multiply 0.025 by 100 and you get 2.5%
4.
Divide 4 by 8 and you get 0.5.
Divide 0.5 by 100 and you get 50%.
5.
Divide 12/16 and you get 0.75.
Multiply 0.75 by 100 and you get 75%.
