Candace has $15 more than Amar. Their combined my money totals $85. Which system of equations represents this equation?

See explanation

Step-by-step explanation:

Let Amara money be represented by a

Since Candace has $15 more than Amar. Therefore, Candace money will be = a + 15

Their total money will be 85 and this can be represented in an equation as:

a + (a + 15) = 85.

a + a + 15 = 85

2a + 15 = 85

2a = 85 - 15

2a = 70

a = 35

Amar money = $35

Candace money = $35 + $15 = $50

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
