<h3>
The cost of each burrito platters is $ 41 and cost of each taco platter is $ 20</h3>
<em><u>Solution:</u></em>
Let "a" be the cost of each burrito platters sold
Let "b" be the cost of each taco platters sold
<em><u>She spent $203 on 3 burrito platters and 4 taco platters</u></em>
<em><u>Thus we frame a equation as:</u></em>
3 burrito platters x cost of each burrito platters + 4 taco platters x cost of each taco platters = 203

<em><u>For a company meeting, she spent $285 on 5 burrito platters and 4 taco platters</u></em>
<em><u>Thus we frame a equation as:</u></em>
5 burrito platters x cost of each burrito platters + 4 taco platters x cost of each taco platters = 285

<em><u>Let us solve eqn 1 and eqn 2</u></em>
<em><u>Subtract eqn 1 from eqn 2</u></em>
5a + 4b - 3a - 4b = 285 - 203
2a = 82
a = 41
<em><u>Substitute a = 41 in eqn 1</u></em>
3(41) + 4b = 203
123 + 4b = 203
4b = 203 - 123
4b = 80
b = 20
Thus cost of each burrito platters is $ 41 and cost of each taco platter is $ 20
It depends if it is hard back or a soft back
68.7 - t is your expression.
We need to find out the difference between their heights.
Difference means we subtract.
Since she is taller, we are subtracting her height by t. So the answer is 68.7 - t
