The answer to your question is false
I believe it's both a and b
you do them at the end, if it's only 9+10 then just add them.
multiplecation is first, then addition. meaning the answer is 26
To check, we can solve how much sunscreen is in a family sized bottle first. We need to find what is 20% of 12. First, turn 20% into a decimal: 20%/100= 0.2. Now, multiply 0.2 by 12, which is 2.4. Then, you add this to 12 because it is 20% more. 12+2.4= 14.4. Multiply this by 4: 14.4*4=57.6. Since his number is close to 50, he is kinda correct, but a much more reasonable answer would be closer to 60. Hope this helped!
Answer:
k=4h+6hp
Step 1: Flip the equation. 6hp+4h=k
Step 2: Factor out variable h. h(6p+4)=k
Step 3: Divide both sides by 6p+4
h(6p+4) = ( wont let me add the numbers right so lets move on)
6p+4
h=
k
6p+4 <----- is your answer
