Question 5 • Q1 Mathematics 8

Which situation could best be represented by this linear equation? 24x + 38y = 520

Answer

If x represents the number of bracelets and y represents the number of rings, there were 24 more bracelets sold than rings. The total sales were $520.

If x represents the number of bracelets and y represents the number of rings, there were 38 more bracelets sold than rings. The total sales were $520.

If x represents the number of bracelets sold at $24 each and y represents the number of rings sold at $38 each, the total sales were $520.

If x represents the number of bracelets and y represents the number of rings, there were 520 bracelets and rings sold. Bracelets were $24, and rings were $38.

Explanation

In the equation 24x + 38y = 520, each item count is multiplied by its price, and the two amounts add to $520. Choice C matches this: x bracelets cost $24 each and y rings cost $38 each, for total sales of $520. Choices A and B describe differences in the numbers sold, which would require subtraction; D says the total number sold is 520, not the total sales revenue.
