Answer:
252
Step-by-step explanation:
Multiply 350 by the decimal form of 72%. To find the decimal form of 72%, divide 72 by 100 or move every number two places to the right:
72/100 = 0.72
Then multiply 350 by 0.72:
350 x 0.72 = 252

Answer: 40
<u>Step-by-step explanation:</u>
Let x represent the original ratio and y represent the final ratio:
Egg : Tuna
2x 3x
<u> </u> <u> +15 </u> <em>15 tuna were added</em>
2x = y 3x + 15 = 3y <em>y and 3y are the final 1:3 ratio</em>
Now you have a system of equations. I am going to choose the substitution method. "2x" can be substituted for "y" in the second equation:
3x + 15 = 3y
3x + 15 = 3(2x)
3x + 15 = 6x
15 = 3x
5 = x
Egg (final): 2x = 2(5) = 10
Tuna (final): 3x + 15 = 3(5) + 15 = 15 + 15 = 30
Egg (final) + Tuna (final) = Total sandwiches
10 + 30 = 40
