Benito is selling t-shirts for $8 each for his school fund-raiser. so far, he has sold 16 t-shirts. how much more does he need to sell to reach his goal of $200 in sales? three of these equations solve for the number of t-shirts, t, he still needs to sell to reach $200 in sales. which equation does not? answer 1 : t=9answer 2: t=8(t  + 16) = 200answer 3 t=8t  + 128 = 200answer 4: t =8t  + 16 = 200

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
