Answer just one of them at least!

polly buys a drink at a convenience store for $1.80. she also buys a bag of chips.

(a) the ratio of the cost of the chips to the cost of the water is 4: 3. find the cost of the chips.

$

(b) polly has $6 to spend. work out the total amount she spends on a drink and chips as a fraction of the $6. give your answer in its lowest terms.

(c) the $6 is 37.5% less than the amount polly had to spend last week. calculate the amount she had last week.

$

see explanation below

Step-by-step explanation:

In order to do this, you can put and solve this in this way:

we know that the ratio between chips and water is 4:3 so:

Chips/Water = 4/3

Solving for chips:

Chips = 4 Water / 3

Now put the price of the water here, and you should get the price of the chips:

Chips = 4 * 1.8 / 3

Chips = 2.4 $

b) If the chips cost 2.4 and the drink 1.8, the total is 4.2, therefore, the total amount is:

4.2/6 = 2.1/3 = 0.7/1

c) If 6$ is 37.5% then the 100% would be:

6 * 100 / 37.5 = 16$

5050
