**Problem 1 :**

At a candy store you could get 3 giant lollipops for $4.89. How much would it cost to buy 6 lollipops ?

**Solution : **

**Given :** Cost of 3 giant lollipops is $4.89

Then, the cost of 1 giant lollipop is

= 4.89 / 3

= $1.63

The cost of 6 giant lollipops is

= 6 ⋅ 1.63

= $9.78

So, it would cost $9.78 to buy 6 lollipops.

**Problem 2 : **

A pet store was selling mice 6 for $7.02. If they ended up selling 7 mice, how much money would they have earned ?

**Solution : **

**Given :** Cost of 6 mice is $7.02

Then, the cost of 1 mouse is

= 7.02 / 6

= $1.17

The cost of 7 mice is

= 7 ⋅ 1.17

= $8.19

So, if they ended up selling 7 mice, they would have earned $8.19

**Problem 3 **

At the produce store you can buy 2 bags of bananas for $12.46. How much would it cost if you were to buy 6 bags ?

**Solution : **

**Given :** Cost of 2 bags of bananas is $12.46

Then, the cost of 1 bag of bananas is

= 12.46 / 2

= $6.23

The cost of 6 bags of bananas is

= 6 ⋅ 6.23

= $37.38

So, if we were to buy 6 bags of bananas, it would cost $37.38

**Problem 4 :**

At the store Brand A potato chips were $11.92 for 4 bags. Brand B potato chips were $17.34 for 6 bags. Which brand has the cheaper price ?

**Solution : **

Cost of 1 bag is = 11.92 / 4 = $2.98 |
Cost of 1 bag is = 17.34 / 6 = $2.89 |

2.98 > 2.89

Comparing the unit prices, brand B has the cheaper price.

**Problem 5 :**

A supermarket had bags of red grapes for $13.00 for 5. The also had bags of green grapes priced at $5.08 for 2. Which type of grape is most expensive ?

**Solution : **

Cost of 1 bag is = 13.00 / 5 = $2.60 |
Cost of 1 bag is = 5.08 / 2 = $2.54 |

2.60 > 2.54

Comparing the unit prices, reg grape is most expensive.

**Problem 6 :**

A store had 5 packs of paper for $9.25. How much would it cost, if you were to buy 4 packs ?

**Solution : **

**Given :** Cost of 5 packs of paper is $9.25

Then, the cost of 1 pack of paper is

= 9.25 / 5

= $1.85

The cost of 4 packs of paper is

= 4 ⋅ 1.85

= $7.40

So, if we were to buy 4 packs of paper, it would cost $7.40

**Problem 7 :**

Four gallons of gasoline cost $16.80. If you buy 5 gallons of gasoline, how much do you have to pay ?

**Solution : **

**Given :** Cost of 4 gallons of gasoline is $16.80

Then, the cost of 1 gallon of gasoline is

= 16.80 / 4

= $4.20

The cost of 5 gallons of gasoline is

= 5 ⋅ 4.20

.= $21.00

So, if we buy 5 gallons of gasoline, we have to pay $21.00

**Problem 8 :**

In a store, six shirts are sold for $25.50. If you buy 4 shirts, how much do you have to pay ?

**Solution : **

**Given :** Cost of 6 shirts is $25.50

Then, the cost of 1 shirt is

= 25.50 / 6

= $4.25

The cost of 4 shirts is

= 4 ⋅ 4.25

.= $17.00

So, if we buy 4 shirts, we have to pay $17.00
