Maggie has a job working in an office for $9 an hour and another job driving a tractor for $18 an hour. Maggie works at both jobs and earns $630 in one week.

(a) Write an equation that gives the number of hours, x, she worked for $9 per hour and the number of hours, y, she worked for $18 per hour.

(b) Find the x- and y-intercepts for this equation.

x-intercept (x, y)
y-intercept (x, y)

@kelliegirl33  do you have any idea ?

anonymous · Answer

9x + 18y = 630

x intercept : 
9x + 18(0) = 630
x = 630/9
x = 70 <-- x intercept

y intercept  :
9(0) + 18y = 630
18y = 630
y = 630/18
y = 35 <-- y intercept

9x + 18y = 630
9(70) + 18(35) = 630

not sure about the hours for each......

anonymous · Answer

x intercept = (70,0)
y intercept = (0,35)

thank you ive been struggling with these problems for weeks

then it asks me this 
(d) From the graph, find how many hours she worked at $18 if she worked 38 hours at $9 per hour.
