4 A bricklayer lays 1500 bricks in an 8-hour day. Assuming he continues to work at the same rate, calculate:
a how many bricks he would expect to lay in a five-day week
b how long to the nearest hour it would take him to lay 10000 bricks.

answer of a is 7500and the answer of b is53 hours

1/5x+9 2/5y+7

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
