Otis plans to make 3 batches of sidewalk chalk How much plaster of paris does he need

Hep me please

cups plaster of paris.

Step-by-step explanation:

Given:

for one batch of sidewalk chalk = cup plaster of paris.

Number of bathes = 3

We need to find quantity of plaster of paris.

Solution:

For making 1 batch of sidewalk chalk = cup plaster of paris.

For making 3 batches of sidewalk chalk = cup plaster of paris.

Therefore, he needed cups plaster of paris.

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

its 50 miles away from the starting point
