You parents gave you $50 to take your brother and sister to the movies. your ticket cost $7.25 and your siblings cost $4.25. if you spent an additional $20 on soda and popcorn, how much money did you bring home with you? adults: 7.25 seniors: 6.00 children under 8: 4.25

You bring home $14.25 with you.

Step-by-step explanation:

First we add the money spent in movie tickets and snacks.

Your ticket = $7.25

Brother's ticket = $4.25

Sister's ticket = $4.25

Soda and popcorn = $20.00

Total = 7.25 + 4.25 + 4.25 + 20.00 = $35.75

Your parents gave you = $50.00

You spent = $35.75

Balance = 50.00 - 35.75 = $14.25

You bring home $14.25 with you.

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

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
