Practice You bought shoes for $39 that were marked 20%
off. You have to pay
9% tax. What is the total for
the shoes?

$34

Step-by-step explanation:

39 x 0.2 = 7.80, the discount

39 - 7.80 = 31.20

31.20 x 0.09 = 2.80, the tax

31.20 + 2.80 = 34

Total cost for the shoes: $34

24.99 dollars

Step-by-step explanation:

24 is 20 percent of 39

it could be 1,3 and more others to create a cylinder.

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
