Answer: t= 3/2
Step-by-step explanation: 5/ 7 1/2 = 3/2
In order to calculate the total cost of the purchase, we must first assess that there were two items bought, turkey and lamb. Next, we see multiply the cost of the first item by its quantity, so:
cost(T) = 2.15 * 7.89
cost(T) = $16.96
And repeat for the second item:
cost(L) = 1.87 * 7.89
cost (L) = $14.75
Finally, the total cost is the sum of these costs. So
Total = 16.96 + 14.75
Total = $31.71

Percentage wise, we are understanding that 100% of the population equals all 3,600 students, and that only 40% eat cold pizza for breakfast. This means that 60% do not eat cold pizza for breakfast, so:
3600 students x 0.6 (or 60/100) = 2,160 students who do not eat cold pizza for breakfast.
Rounding as accorded to the question, the answer would then be 2,200 students when rounded to the hundredths place.
