The number of waffles there were initially is; 80 waffles
<h3>Simultaneous equations</h3>
Let the number of pancakes be x.
Let the number of waffles be y
Hence, after she baked 45 more waffles, and her grandchildren eat 12 pancakes, what she has is;
- y +45 waffles and x-12 pancakes.
There were 17 more waffles than pancakes.
- y+45 = x-12 +17.......equation (1)
And initially, x = 1.5y
Hence, to determine y, we must substitute x = 1.5y into equation (1)
Therefore, we have;

Given:
A bond with an annual coupon rate of 4.8%, bond value is $970. The bond's current yield can be calculated using this formula:
i = F<em>i</em><em>b
</em><em>
</em>where i = bond <em />yield<em>
</em>F = $970
<em>ib </em>= 4.8%
i = 970*(0.048)
i = $46.56
Step-by-step explanation:
let the University of Miami enrolment be x
so the University of Texas at Austin has three times = 3x
The University of California, Berkley has 3,000 more than twice the number of students at the University of Miami.
this can be translated as = 3000+2x
in total, the enrolment is 96,000
therefore
x+3x+3000+2x=96000
we can now solve for x
6x=96000-3000
6x=93000
divide both sides by 6 we have
x=15500
1. The University of Miami enrolment is 15500 students
2. The University of Texas at Austin has three times = 3x
=3*15500
= 46500 students
3. The University of California, Berkley has
= 3000+2x
= 3000+2(15500)
=3000+46500
=49500 students
