Total Peng's spend on her equipments is $48,915
Further explanation
From the problem given we know that:
Total treadmill bought 26
Price/treadmill $1334
Total stationary bikes bought 19
Price/stationary bike $749
So we can write the expression as follow
Total spend
= (Total treadmill x price/each)+(total stationary bikes x price/each)
= (26 x 1344) + (19 x 749)
to solve the equation we can use standard algorithm as follow:
Total spend on treadmill
1334
26 x
8004
26680+
34684
Total spend on stationary bikes
749
19x
6741
749 +
14231
Total spend
[tex]=\boxed {(26 \times1334) +(19 \times749)\ }\\ =\boxed {34684+14321)\ }\\ =\boxed {48915\ }[/tex]
So, Peng spent $48,915 on her equipments.
