kherson [118]

d=drinks
p=pretzels
1st eq. 3d+3p=9.00
2nd eq. 4d+2p=8.50

multiply 1st eq by 2

6d+6p=18.00

multiply 2nd eq by 3
12d+6p=25.50
subtract
-6d=-7.50
d=1.25
3p=9.00-3d

3p=9-3.75

3p=5.25
p=1.75
price of a pretzel=$1.75

price of a drink = $1.25

Answer:

Part a) $7.536\ m$

Part b) $\$34.14$

Step-by-step explanation:

Part 6)

a) How much edging is needed?

we know that

To find out how much edging is needed determine the circumference of the circular garden

The circumference of the circular garden is equal to

$C=\pi D$

where

D is the diameter

we have

$D=2.4\ m$

assume

$\pi =3.14$

substitute

$C=(3.14)(2.4)$

$C=7.536\ m$

Part b) we know that

To find out the cost to edge the garden, multiply the length of edging plastic needed by the cost of $4.53 per meter

$(7.536\ m)(4.53\ \$/m)=\$34.14$
