Question

Enrique predicts that he can make additional money from sales of accessories and services for computer products sold by his store. The table at the right shows predicted percent returns for such sales. For example, if the store makes x dollars selling computer products, Enrique predicts the store will make 0.05x dollars ($0.05) from selling accessories. In January and February of this year, the store made $2,500 from sales of accessories and services. Let x represent the amount the store will make from sales of computer products from March through December. Write an equation that represents the predicted amount y that the store will make from sales of accessories and services for the entire year.

A. Write the equation in standard form that shows the number of x of desktop computers and the number y of tablets that Enrique can buy.

Options:
a) 0.05x = 2,500
b) y = 0.05x + 2,500
c) y = 2,500 - 0.05x
d) 2,500x = 0.05y

Answer 1

The equation that represents the predicted amount y the store will make from sales of accessories and services for the entire year, considering $2,500 already made in January and February, is y = 0.05x + 2,500.

Step-by-step explanation:

Enrique predicts additional revenue from sales of accessories and services related to computer products. He estimates that if the store sells x dollars worth of computer products, the store will make 0.05x dollars from selling accessories. With $2,500 earned from accessories and services in January and February, we aim to find the predicted amount y the store makes from these sales for the entire year. To represent this prediction for March through December, we use the linear equation y = 0.05x + 2,500.

To translate this into an equation that includes the entire year, the term 0.05x accounts for the predicted sales from March to December, and 2,500 accounts for the actual sales in January and February. Combining these, we get the equation that represents the predicted amount y for the entire year: y = 0.05x + 2,500. Thus, the correct option is b).
