The full price of a pair of trainers is £42. The price is reduced by 15% in a sale. Work out the sale price of the trainers

35.7

Step-by-step explanation:

Find the discount

42 * .15 = 6.3

Take this from the original price

42-6.3 =35.7

The sale price is 35.7

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

answer is x<
