Let assume
X for ice cream cones
Y for sundaes
X+Y=172
X=172-Y……..*
1.10X+2.35Y=294.20
Substitute * in the above equation
1.10(172-Y)+2.35Y=294.20
189.2-1.10Y+2.35Y=294.20
1.25Y=294.20-189.2
1.25Y=105 divide both sides by 1.25
Y=84
The substitute Y value in * equation
X=172-84
X=88
Therefore
88 ice cream cones and 84 sundaes were sold!!
56.70 because 35%of $42 is 14.70 and if you add those two together you get 56.70
Answer:
0
Step-by-step explanation:
it looks like the term is increasing by 2 each time
The formula for point slope is:
y-y1=m(x-x1)
m is your slope: 3; plug in 4 for y1 and 2 for x1
y - 4=3(x-2)
