1. The equation c = 2.95g shows how much it costs to buy gas at a gas station on a
Karolina [17]

Answer:

see the procedure

Step-by-step explanation:

we have

c=2.95g

where

c -----> the cost in dollars

g ----> the number gallons of gas purchased

1) For g=1 gal

substitute the value of g in the equation and solve for c

c=2.95(1)

c=\$2.95

The pair (1,2.95) fit the relationship

2) For g=3 gal

substitute the value of g in the equation and solve for c

c=2.95(3)

c=\$8.85

The pair (3,8.85) fit the relationship

3) For g=5 gal

substitute the value of g in the equation and solve for c

c=2.95(5)

c=\$14.75

The pair (5,14.75) fit the relationship

4) For c=$20.65

substitute the value of c in the equation and solve for g

20.65=2.95g

g=20.65/2.95

g=7\ gal

The pair (7,20.65) fit the relationship

Two sizes of cans of beans are similar. The thickness of the walls and bases are the same in both cans. The ratio of their surfa
agasfer [191]

Answer:

It costs  $0.216  to make smaller can and $0.324 to make larger can

Step-by-step explanation:

Given:

The ratio of the surface areas = 4:9

Area of smaller cans =  36 sq in

Cost  = $0.006 per square inch  

To Find:

how much does it cost to make each can = ?

Solution:

Lets the area of the larger can be x

the ratio is  4 :  9

then 4x =  9.(36)

4x = 216

x = \frac{216}{4}

x =  54

The area of the larger can is 54 sq in

Now the cost of making the smaller can  =   36 \times  0.006 = $0.216

The cost of making the Larger can = 54 \times 0.006 =$0.324
