Some of the notebooks were $3.50 each and the others were $4.25 each. If x represents the number of least expensive notebooks, which equation can be used to find the number of least expensive notebooks purchased? a) $7.75(7 – x) = $34.50 b) $3.50(x – 7) + 4.25x = $34.50. c) $3.50x + $4.25(8 – x) = $34.50 d) $3.50x + $4.25(x – 8) = $34.50 ................
