Fabio and Gwen are saving money to buy a new gaming station. They need at least $510 to purchase the new gaming station. Gwen weeds yards and Fabio walks dogs to raise money. Gwen charges $12 each time she weeds a yard and Fabio charges $9 each time he walks a dog. The number of dog walks that Fabio has scheduled is no more than twice the number of yards Gwen has scheduled to weed. Fabio will walk at least 25 dogs. Write a set of constraints to model the problem, with x representing the number of lawns weeded and y representing the number of dogs walked.

Answers

Answer:

$12x + 9y \geq = 510\n y\leq 2x\n y \geq 25$

Step-by-step explanation:

If x represents the number of lawns and 'y' represents the number of dogs that Fabio walked then:

The amount of money raised by Fabio plus the amount of money raised by Gwen must be greater than or equal to $ 510.

$12x + 9y \geq = 510$

The number of dogs that Fabio will walk is less than or equal to twice the number of yards of lawn cleared by Gwen.

$y\leq 2x$

Fabio will walk at least 25 dogs

$y \geq 25$

Finally, the restrictions are:

$12x + 9y \geq = 510\n y\leq 2x\n y \geq 25$

for 15 weeks, sue put the same amount of money in a jar. then she took $9 out to spend on a friend's birthday present. she had $21 left. how much did she put in each week?

Answers

$x=amount\ she\ put\ in\ each\ week \n 15x-9=21 \n 15x=30 \n x= (30)/(15) \n x=2 \n \boxed{2\ dollars\ each\ week}$

$2 because you add the 9 back to the 21 then divide by 15 to get 2

Drag each tile to the correct box.Dominic is a server at a restaurant. Each dish at the restaurant costs $8. A sales tax of 8% is charged. The total bill amount includes the sales tax of the meal.

Dominic earns tips left by customers. The amount of money tipped can be represented by a percentage of the total bill.

Order the tip amounts from least to greatest tip, in dollars.

5 dishes
17.5% tip

6 dishes
14% tip

7 dishes
11% tip

4 dishes
20% tip

Answers

Final answer:

To find the tip amounts in dollars, calculate the total bill amount for each scenario by adding the cost of the dishes and the sales tax. Then, multiply the total bill amount by the given tip percentages to find the tip amounts. Order the tip amounts from least to greatest.

Explanation:

To determine the tip amount in dollars, you need to find the total bill amount first. The total bill amount includes the cost of the dishes and the sales tax. The sales tax is 8% of the cost of each dish. Let's calculate the total bill amount for each scenario:

For 5 dishes, the total bill amount is $8 x 5 = $40. The sales tax is 8% of $40, which is $40 x 0.08 = $3.20. The tip amount is 17.5% of $40 + $3.20 = $7.20.
For 6 dishes, the total bill amount is $8 x 6 = $48. The sales tax is 8% of $48, which is $48 x 0.08 = $3.84. The tip amount is 14% of $48 + $3.84 = $7.92.
For 7 dishes, the total bill amount is $8 x 7 = $56. The sales tax is 8% of $56, which is $56 x 0.08 = $4.48. The tip amount is 11% of $56 + $4.48 = $8.16.
For 4 dishes, the total bill amount is $8 x 4 = $32. The sales tax is 8% of $32, which is $32 x 0.08 = $2.56. The tip amount is 20% of $32 + $2.56 = $7.12.
