Allam just finished a great meal at a restaurant in wisconsin. the sales tax in wisconsin is 5 percent, and it is customary to leave a tip of 15 percent for the server. the tip amount is calculated on the price of the meal before the tax is applied. (sales tax is not calculated on tips.)
if allam ordered a $15 meal, how much money will he have to pay with tax and tip?

18

Step-by-step explanation

First Step---Figure out Tax

tax = 15 dollars * .05 tax rate

 =0.75

Second Step--Figure out Tip

tip = 15 dollars times 0.15 tip rate

 =2.25

Bill + tax+ tip

total = 15+0.75+2.25 = 18

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
