Apples cost $1.39 per kilogram. If you have $6.00,
can you purchase a 3.75 kg bag of these apples?
Explain how you could make an estimate to be
sure, before you purchase the apples.
Find the cost of the apples.

Yes

Step-by-step explanation:

We know that 1.39 is less than 1.5 and 3.75 is less than 4.

Hence the price of 3.75kg is going to be less than: 4*1.5=$6

Given that apples cost  $1.39 per kilogram, then the price of 3.75 kg of apples is  3.75*1.39=$ 5.2125.

Because 5.2125 is actually less than $6

This means that $6 can buy 3.75 kg of apples.

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
