Which equation can be used to determine p, the cost of s swimsuits

1 answer:

6 0

is there more to the question? because in order find "s" I need to know the question but a majority of the time you would multiply the amount of money the suit cost by the quantity.

Solve the problem. When going more than 38 miles per hour, the gas mileage of a certain car fits the model where x is the speed

Lubov Fominskaja [6]

Answer:

73 mph

Step-by-step explanation:

The question seems to be incomplete because the model is missing, I found a similar question with the addition of the model, so if we can solve it (see attached image).

We have that the model would be:

y = 43.81 - 0.395 * x

We need to solve for x, if y = 15

Replacing:

15 = 43.81 - 0.395 * x

Solving for x we have:

0.395 * x = 43.81 - 15

0.395 * x = 28.81

x = 28.81 / 0.395

x = 72.9

We are asked to round to the nearest number therefore x = 73.

The car will average 15 miles per gallon at the speed of 73 miles per hour.
