Answer:
Lisa earns more money because John makes $16 while Lisa makes $18.
X=price of one jumbo popcorn
y=price of one chocolate chip cookies
$5.00=$5.00(100 cts / $)=500 cts
$6.00=$6.00(100 cts / $)=600 cts
We suggest this system of equations:
x+2y=500
x+4y=600
we solve this system of equations by reduction method.
-(x+2y=500)
x+4y=600
----------------------
2y=100 ⇒ y=100/2=50
x+2y=500
x+2(50)=500
x+100=500
x=500-100
x=400
solution: one chocolate chip cookie cost 50 cts.
Answer:
62 degrees
Step-by-step explanation:
Points (12,440 and (20,20)
Slope = -3
Equation of line: y - 44 = -3(x - 12)
Plug in x = 6 to get y = 62.
