Solution :
Original price of a toy( A ) = £50
Increased price = £65
price difference = £65 - £50 =£15
Increased % = ( difference × 100 )/A
= ( 15 × 100 )/50
= 30%

The jeweler bought it for (1235.55 * 73.5) = 90812.925...expenses
and the jeweler sold it for (1376.44 * 73.5) = 101168.34...revenue
profit = revenue - expenses
profit = 101168.34 - 90812.925 = 10355.415 rounds to 10,355.42 <==
A = ½ (b × h) is the formula! Let me know if I can help further:)
RS and TS are congruent as they are the sides opposite the 20 degree angles. That mean TR > TS so "A" is the only answer that is correct.
The answer is 17/5. You have to take the whole number, multiply that by the denominator. Then add that number to the numerator to get the new numerator and the denominator stays the same as before (5)
