Marta's customer bought 4 large oranges at $0.75 each and 8 small oranges at $0.50 each plus tax was a total of $7.49. She used t to represent the amount of tax. Explain her errors in the diagram. 2-3 sentences.

Question

t (on top)
7.49 (on left)
0.75(8) (in middle)
0.50(4) (on right)

Answer 1

Marta made two errors in the diagram. First, she incorrectly multiplied the quantity of large oranges (8) by the price per orange ($0.75). Second, she incorrectly multiplied the quantity of small oranges (4) by the price per orange ($0.50). These errors resulted in an incorrect total cost calculation, leading to an inaccurate representation of the tax amount.
