The price of gas rose from $2.40 per gallon in january to $3.00 per gallon in April. What was the percent increase based on the original price? A: 20%
B: 25%
C: 60%
D: 80%

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

answer

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
