Four gallons of gasoline cost $14. A customer will get
gallon for $3.50.

A customer will get
gallons for $7.00.

A customer will get
gallons for $14.00.

A customer will pay $
for 6 gallons.

A customer will get 1 gallon for $3.50.

A customer will pay $ 21 for 6 gallons.

A customer will get 4 gallons for $14.00.

A customer will get 2 gallons for $7.00.

Step-by-step explanation:

This is solved using the unitary method .

Four gallons cost $ 14

1 gallon costs $ 14/4= $ 3.5

6 gallons cost = $ $ 14/4 *6= $ 21

2 gallons cost = $ 14/4 *2= $14/2= $ 7

A customer will get 1 gallon for $3.50.

A customer will pay $ 21 for 6 gallons.

A customer will get 4 gallons for $14.00.

A customer will get 2 gallons for $7.00.

This can be found out by using the direct ratio as well.

Gallons                   Cost

4                               $14

1                                x

Using cross product

x*4= $ 14*1

x= $ 14/4 = $3.5

The same can be applied to find the rest and we get the same answers.

y=mx+b is the final answer!   : )

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
