Zalia meets her friend at the science museum to see a special exhibition. the admission to the museum is $12.50 per person plus tax. zalia pays for herself and her friend. they have lunch at the museum’s cafe. zalia has a sandwich for $5.95, an apple for $1.25 and a drink for $1.69. she is charged tax and also tips her server 15%. if tax is 7.25%, how much did zalia pay all total for her day at the science museum? a. $41.43 b. $37.68 c. $36.35 d. $24.27

The correct answer is:

b. $37.68

Explanation:

Each admission ticket is 12.50 plus tax.  2 tickets at 12.50 each is

2(12.50) = 25

Tax for this is 7.25%; 7.25% = 7.25/100 = 0.0725;

25+25(0.0725) = 25(1.0725) = 26.82

For lunch, she spent

5.95+1.25+1.69 = $8.89.

Tax for this would be 0.0725(8.89) = $0.64

15% tip on this would be 8.89(0.15) = $1.33

This gives us

8.89+0.64+1.33 = $10.86 for lunch.

This is a total of

26.82+10.86 = $37.68.

b.  $37.68

Step-by-step explanation:

Edge 2020

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

maya’s expression will generate the wrong sum because she violated the commutative property.
