We make two sets of equations: x + y = 106 and 0.05x + 0.25y = 13.70. I will solve by substitution. Subtract "x" from both sides of x + y = 106 to convert it to slope intercept form, so y = 106 - x. Substitute y = 106 - x into 0.05x + 0.25y = 13.70, so 0.05x + 0.25(106 - x) = 13.70. Solve for 0.05x + 0.25(106 - x) = 13.70, so 26.5 - 0.2x = 13.7, then x = 64. Substitute 64 into x + y = 106, so 64 + y = 106, then y = 42. There is 64 nickels and 42 quarters.
3/8
A fraction is a mathematical symbol to represent part of a whole. There are 8 tulips, which is the whole. 3 is the part. So it is 3/8. Hope this helps! :)
<span>The correct answer is option D. i.e. ounce. Because ounce is a unit of measurement of mass where all the other options are the units of measurement of volume i.e. liter, gallon and cup. Thus, ounce is the odd one out and doesnt belong here.</span>
