#21: (4•4) + (7•7)= (c•c)
16+49= (c•c)
65=(c•c)
_/65= c
#22: 22+90= 112
180-112= 68
68
#23: (3.5•3.5) + (4.7•4.7) = (c•c)
12.25 + 22.09= (c•c)

_/34.34= c
#24: 22+90= 112
180-112= 68

Miles per hour is the only correct answer
The sale price was $9,750 and we know that this amount is 90 % of the retail price. To solve this, let us formulate equation such as below:
Let RP be the retail price.
Let SP be the sale price.
Therefore,
RP x 0.9 = SP
RP x 0.9 = $9,750
RP = $9,750 / 0.9
RP = $ 10,833.33
The retail price was $10,833.33.
