for per meal - $100

for 50 meals - $100 × 50 = $500//

x = $900/$100

x = 9//

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3

so, converting firstly the mixed fractions to improper fractions and then "adding".
