Svetlanka [38]

Answer:

The equation to determine the salary every given number of weeks is 14x2 ^ X = Y, and after 12 weeks, the counselor's salary will be $ 57,344.

Step-by-step explanation:

Since the initial starting salary for a summer camp counselor is $ 14 per week, and starting with the first week, the salary doubles to encourage the counselor to work for the entire summer, to write an equation that models the salary (y) of the camp counselor per week (x), and determine, if the camp runs for 12 weeks, how much would a camp counselor make, the following calculations should be performed:

14x2 ^ X = Y

14x2 ^ 12 = Y

14x4,096 = Y

57344 = Y

Therefore, the equation to determine the salary every given number of weeks is 14x2 ^ X = Y, and after 12 weeks, the counselor's salary will be $ 57,344.

You need a 70% alcohol solution. On hand, you have a 420 mL of a 85% alcohol mixture. How much pure water will you need to add t
Nimfa-mama [501]

Answer:

Pure water =74.1 mL

Step-by-step explanation:

You need 420 mL of a 70% alcohol solution.

420 mL of solution and 70% of it should be alcohol.

So,

420 * 70/100 mL

= 420 * 0.7

= 294 mL of alcohol and the rest should be water.

On hand, you have a 85% alcohol mixture.

The alcohol can only come from the 85% mixture. So, how much of 85% alcohol do we need to get 294 mL of alcohol:

Let

y = alcohol solution needed

85% of y = 294

85/100 * y = 294

y = 294 ÷ 85/100

y = 294 × 100/85

y = 29,400/85

y = 345.88235294117

Approximately, 345.9mL

The rest of 420 mL solution has to be pure water

Pure water = 420 mL - 345.9mL

= 74.1 mL

Pure water =74.1 mL
