  3. 366 packs of permanent markers at $14.95\$14.95 per pack
  4. 444 magnetic whiteboards at $22.45\$22.45 each

Cevap

The correct order from least expensive to most expensive is: 55 boxes of classification folders ($89.25\$89.25), 1212 packs of highlighters ($89.40\$89.40), 66 packs of permanent markers ($89.70\$89.70), and 44 magnetic whiteboards ($89.80\$89.80).
The total cost for each order is found by multiplying the quantity by the price per item. The folders cost $89.25\$89.25 (5×$17.855 \times \$17.85). The highlighters cost $89.40\$89.40 (12×$7.4512 \times \$7.45). The markers cost $89.70\$89.70 (6×$14.956 \times \$14.95). The whiteboards cost $89.80\$89.80 (4×$22.454 \times \$22.45). Ordering these decimal values from least to greatest gives the correct sequence.
