Answer:</h2>
<u><em>Let m be the amount each mom can paint and d be the amount each daughter can paint.</em></u>
<u><em>On the first day, 8 mothers were painting so the mothers painted 8m square feet. 12 daughters also painted so the daughters painted 12d square feet. The total amount painted on the first day is then 8m+12d square feet. Since 220 square feet was painted on the first day, then 8m+12d=220. Dividing both sides by 4 gives a simplified equation of 2m+3d=55.</em></u>
<u><em>On the second day, 6 mothers were painting so the mothers painted 6m square feet. 8 daughters also painted so the daughters painted 8d square feet. The total amount painted on the second day is then 6m+8d square feet. Since 152 square feet was painted on the second day, then 6m+8d=152</em></u>
<u><em /></u>
<u><em>Multiply the first equation by -3 and then add it to the second equation to eliminate m and solve for d:</em></u>
<u><em>d=13</em></u>
<u><em>2m+3d=55</em></u>
<u><em>2m+3(13)=55</em></u>
<u><em>2m+39=55</em></u>
<u><em>2m=16</em></u>
<u><em>m=8</em></u>
<u><em>Therefore each mom painted 8 square feet and each daughter painted 13 square feet.</em></u>
It would be 27/20 or, simplified, 1 and 7/20

Answer:
248
Step-by-step explanation:
Solution for What is 400 percent of 62:
400 percent *62 =
(400:100)*62 =
(400*62):100 =
24800:100 = 248
Now we have: 400 percent of 62 = 248
Question: What is 400 percent of 62?
Percentage solution with steps:
Step 1: Our output value is 62.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$62=100\%.
Step 4: Similarly, x=400\%.
Step 5: This results in a pair of simple equations:
62=100\%(1).
x=400\%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
\frac{62}{x}=\frac{100\%}{400\%}
Step 7: Again, the reciprocal of both sides gives
\frac{x}{62}=\frac{400}{100}
\Rightarrow x=248
Therefore, 400 of 62 is 248
