If b represents the number of bikes and s represents the number of skateboards Donte is planning to repair to save up money for college, the total number of things he can repair in a day will be expressed as the sum of number of bikes and number of skateboards i.e b+s = T
Given that He can repair up to 2 bikes per day, the total and 4 skateboards per day this means that b = 2 and s = 4
Total number of thing's he can repair in a day given this amount T = 2 + 4 = 6 things
–5 × 0.75 × 20 could be rewritten (applying the associative property) as –5 × (0.75 × 20). I chose this configuration because 0.75 * 20 is 15. Next, evaluate -5(15). This is -75. This matches Answer D.
