Explanation Given: Jorge makes 5% commission on telephone sales and 6% commission on showroom sales. The sales totaled $40,000 and his commission was $2,250. Unknown Facts: Let x denote amount of sales Jorge made by telephone and y denote the amount of sales Jorge made in showroom. Relationships: The sales totaled up to $40,000 that is, x + y = 40000 . Jorge makes 5% commission on telephone sales and 6% commission on showroom sales that totaled to $2,250 that is, 0.05 x + 0.06 y = 2250 . Estimation: If the 6 % of commission was made for $40,000 the commission is 0.06 × 40 , 000 = 2 , 400 . Since the commission received by Jorge is $2,250, most of the sales was on showroom. Calculation: Consider the two equations x + y = 40 , 000 and 0.05 x + 0.06 y = 2 , 250 . Rewrite the first equation x + y = 40 , 000 as, x + y = 40 , 000 x = 40 , 000 − y . Substitute x = 40 , 000 − y in 0.05 x + 0.06 y = 2250 as, 0

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…
