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$

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

step-by-step explanation:

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
