Question

A restaurant sells tokens that customers used to play games while waiting for their orders which option is the best deal justify your answer 1 token= $0.50
10 tokens= $5.00
25 tokens= $10.00
50 tokens= $25.00
90 tokens= $40.00

Answer 1

It would be 90 tokens, let me show you why
0.50 * 10 = $5 (this one would be equal)
0.50 *25 = $12.5 ($2.5 saved)
0.50 * 50 = $25 (this one is also equal)
0.50 * 90 = $45 ($5 saved)
on 90 tokens you save $5 which is the most
