Answer:
$89.64
Step-by-step explanation:
First, you want to find your unit rate.
To do that, simply just divide what you know (cost/amount):
29.88/12
= 2.49
This means that one role of tape costs $2.49.
Now that we know that, you can simply just solve for value "c":
c = 2.49(36)
c = 89.64
first you must convert 1/5 to a % 1/5 = 20% fruit cakes 50% party cakes 100%- 70%= 30% left for sponge cakes hope this helps

using a graph tool
see the attached figures
case A)
y>x+1
y<=10
x>=0
case B)
y>=x+1
y>=10
x>=0
case C)
y>=x+1
y<10
x>=0
case D)
y<x+1
y<=10
x>=0
the answer is the case A)y>x+1 y<=10x>=0
Part A
The pen has a rectangular shape of length
l and width, say
w.
The perimeter (the fencing) of this rectangle is
2l+2w, as in the rectangle we have 2 opposing sides of length
l and 2 opposing sides of length
w.
This means that 2l+2w=400
subtract 2l from both sides:
2w=400-2l
divide by 2:
w=200-l, so we find that the width is 200-l.
part B
we are asked to find w when l=80 ft,
since we have
w=200-l, we can find w for l=80 ft by substituting :
w=200-l=200-80=120 (feet)
Part C
The area of the pen when l=90 feet is:

(square feet)
