Question 4

The number of calories for each item in a typical fast food lunch is a quarter-pound hamburger, 430 calories; large French fries, 510 calories; a small vanilla milkshake, 640 calories. Find the total number of calories for this fast food lunch.

Accepted Answer

To find the total number of calories, we need to add the calories for each item:
430 + 510 + 640 = 1580
Therefore, the best choice is C, with a total of 1580 calories.

Question 5

Suppose that in a recent year, there were 94,073 twin births in a country, 6857 triplet births, 623 quadruplet deliveries, and 84 quintuplet and higher-order multiple births. Find the total number of multiple births during the year.

Accepted Answer

To find the total number of multiple births, we add the number of twin births, triplet births, quadruplet deliveries, and quintuplet and higher-order multiple births.

94,073 twin births + 6,857 triplet births + 623 quadruplet deliveries + 84 quintuplet and higher-order multiple births

= 101,637 multiple births

Therefore, the answer is B) 101,637 multiple births.

Question 6

For the following numbers, (i) use a calculator to add; and (ii) estimate the sum by rounding the numbers to the nearest ten-thousand and adding. 82,137

217,570
The estimated sum is also 217,570. 
Comparing our estimated sum and the sum calculated using a calculator, we can see that choice (C) is the best option as it has both the closest estimated sum and calculated sum.
