Emily and Molly are selling pies for a school fundraiser. Customers can buy cherry pies and lemon pies. Emily sold 4 cherry pies
and 1 lemon pie for a total of $30. Molly sold 8 cherry pies and 6 lemon pies for a total of $100. What is the cost for one CHERRY pie
1 answer:
Answer:
<h2>cherry pie = 5</h2><h2>lemon pie =10</h2>
Step-by-step explanation:
Step one:
let cherry be x
and lemon be y
the systems of the equation for the solution is given as
4x+y=30-----------1
8x+6y=100------2
Step two:
solve the equation simultaneously by substitution we have
4x+y=30
y=30-4x
put y=30-4x in equation 2
8x+6(30-4x)=100
8x+180-24x=100
8x-24x=100-180
-16x=-80
x=80/16
x=5
put x=4 in y=30-4x
y=30-4(5).
y=30-20
y=10

10*10=100 so 100 is your answer
This is a difference of perfect square so you get (2x+6)(2x-6)=0, solving will give you 3,-3
(2+2):2x4:16-10x2:2x3=x
4:2x4+16-10x1x3=x
8+16-30=x
-6=x
x=-6

I help the my answer can help you
The answer is the fourth line because it starts with 1 and then you have to subtract 3 from 1 (1-3) and you get -2
29990
10%=29990/10=2999
1%=2999/10=299.90
0.5%=299.90/2=149.95
6%=299.90x6=1799.40
6.5%=1799.50+149.95=$1949.35 tax
total +tax
29990+1949.35=$31395.35
