Part a) Shop Smart

we know that
24 packs (2 for $9)
total cans (24*2)=48

Find the unit price for the can
by using proportion
$\frac{48}{9} = \frac{1}{x} \\ \\ 48*x=9 \\ \\ x=0.1875$

the ratio of the number of cans to the price in the Shop Smart is equal to
$ 0.19

per can

Part b) Super Saver

we know that
12 packs (4 for $10)
total cans (12*4)=48

Find the unit price for the can
by using proportion
$\frac{48}{10} = \frac{1}{x} \\ \\ 48*x=10 \\ \\ x=0.2083$

the ratio of the number of cans to the price in the Shop Smart is equal to
$ 0.21

per can

Part c) Price Buster

we know that
12 packs (3 for $9)
total cans (12*3)=36

Find the unit price for the can
by using proportion
$\frac{36}{9} = \frac{1}{x} \\ \\ 36*x=9 \\ \\ x=0.25$

the ratio of the number of cans to the price in the Shop Smart is equal to
$ 0.25

per can

Answer from: angelmosby9

a)9:48

b)10:48

c)9:36

Step-by-step explanation:

Find the ratio of the number of cans to the price.

Shop Smart: 24 packs (2 for $9)

No. of cans in 1 pack = 24

No. of cans in 2 packs = $24 \times 2 = 48$

Cost of 48 cans = $9

Cost of 1 can = $\frac{9}{48}$

So, the ratio of the number of cans to the price is 9:48

Super Saver: 12 packs (4 for $10)

No. of cans in 1 pack = 12

No. of cans in 4 packs = $12 \times 4 = 48$

Cost of 48 cans = $10

Cost of 1 can = $\frac{10}{48}$

So, the ratio of the number of cans to the price is 10:48

Price Buster: 12 packs (3 for $9)

No. of cans in 1 pack = 12

No. of cans in 3 packs = $12 \times 3 = 36$

Cost of 36 cans = $9

Cost of 1 can = $\frac{9}{36}$

So, the ratio of the number of cans to the price is 9:36

Answer from: Quest

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2 = -20

divide by -2 on each side

-2x^2 /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
