To get to zoo from the school the kids have to ride some buses if there are 7 buses and each bus have three adult supervisors to god the children how many supervisor are there in total

There are 21 supervisors in total

Solution:

Given that, To get to zoo from the school the kids have to ride some buses

There are 7 buses and each bus have three adult supervisors to guard the children

To find: Number of supervisors in total

From given,

Total number of buses = 7

Number of supervisor in 1 bus = 3

Therefore, total number of supervisors can be found by multiplying total number of buses with number of supervisors in 1 bus

Substituting the values we get,

Thus there are 21 supervisors in total

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
