Answer:
1050
Step-by-step explanation:
So, we know 4/5 of a gallon can paint 280ft^2, but we don't know how much each gallon can paint, so to find x, do this
4/5x=280ft^2, next multiply both sides by 5/4 to get x by itself
x=350
Now multiply x by 3 to get your new answer.
350*3=1050

4.50 per walk
At least 50
we can write an equation to solve for how many walks, w,
4.50w = 50
divide both sides by 4.50
w = 11.111...
That is, he will have to walk about 12 times to earn at least $50 when charging $4.50 for a walk with the dogs.
Hope this helps :)
138 short sleve shirts
step 1) add up the ratio of short to long sleve shirts: 3 + 7 = 10
step 2) divide the total # of shirts by 10: 460 / 10 = 46
step 3) because you are finding how many short sleeve shirts are sold, you multiply 46 x 3 = 138 short sleave shirts
