Mia spent $66 buying fabric that cost $7.50 per yard how many yards of fabric to buy how do you know that your answer is reasonable

8.8

Step-by-step explanation:

Total amount spent on fabric= $66

Cost per yard of the fabric= $7.50

To know the amount of yards that Mia buys, we divide the total amount Mia spent on fabric by the cost per yard of the fabric. This will be:

$66/$7.50 = 8.8

Mia bought 8.8 yards of fabric.

To know my answer is correct and reasonable, I will multiply 8.8 by 7.5 to know if I'll get the total amount Mia spent on the fabric.

$8.8 × 7.5= $66

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
