IMPLEMENTATION: The cost of the keyboards is 6$149.97¼$899.82.
The cost of the digital drums is 3$69.97¼$209.91. Add the two answers:
$899.82þ$209.91¼$1109.73. Hence, the total cost of 6 keyboards and 3
digital drums is $1109.73.EVALUATION: Estimate the answer: Keyboards: 6$150¼$900, Digital
drums: 3$70¼$210, Total cost: $900þ$210¼$1110. The estimated cost
of $1110 is close to the computed actual cost of $1109.73; therefore, the
answer is probably correct.Try These
