A local charity held a crafts fair selling donated , handmade items. Total proceeds from the sale were 2605. A total of 89 items were sold, some at 20 each and the rest at 35 each. Let x be the number of 20 items and y the number of 35 items . How many items sold at 35?

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

part a: 1.08

part b: 27.59

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
