Step-by-step explanation:
Answer: C
Step-by-step explanation:
Your answer is correct! When you multiply 2 matrices, the inner dimensions have to be equal. If they are equal, the resulting dimensions would be the outer dimentions.
(<u>3</u>×4)(4×<u>5</u>)
Since the inner (bolded) dimensions are the same, in this case 4×4, we know these matrices can be multiplied.
Since these matrices can be multiplied, the product will be 3×5, the underlined outer dimensions.
Okay. So for this equation, she would make $60, plus $5.25 in tips each hour. So for this, she would get $60 + 5.25h. Plug in 4 hours, and she would make $21 off of tips, plus the $60, which brings her up to $81 total. The answer is C.
