During one summer james mowed an average of 15 lawns each week for 12 weeks. he charged an average of $35 per lawn. about how much did james earn

$6,300

Step-by-step explanation:

Number of lawns mowed per week = 15

Total number of weeks = 12

Total number of lawns mowed during summer = number of lawns mowed per week * total number of weeks; 15*12 = 180 lawns

Price of mowing 1 lawn = $35

Total money earned for mowing 180 lawns = price per lawn * total number of lawns mowed;

Earnings = $35* 180 = $6,300

Therefore , James earned $6,300

i think c. but don't trust it.

step-by-step explanation:

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
