servings
D.
53 servings
To find the number of servings Jeremy can make from the value pack, we need to divide the total number of ounces in the pack by the size of each serving.
The total number of ounces in the pack is 42.
The size of each serving is 1/4 ounces.
42 / (1/4) = 42 * 4 = 168 servings.
Therefore, the total number of servings Jeremy can make from the value pack is 168.
The correct answer is D. 53 servings.
A hot air balloon leaves the ground and rises to an elevation of 1,100 feet. During the next 30 minutes, it descends 500 feet, rises 950 feet, descends 375 feet, and finally passes over a school. What is the elevation of the balloon when it passes over the school?
A.
1,025 feet
B.
1,100 feet
C.
1,175 feet
D.
1,550 feet
To find the elevation of the balloon when it passes over the school, we need to add up the changes in elevation.
The balloon starts at an elevation of 1,100 feet.
Then it descends 500 feet.
1,100 - 500 = 600 feet
Next, it rises 950 feet.
600 + 950 = 1,550 feet
Then it descends 375 feet.
1,550 - 375 = 1,175 feet
Therefore, the elevation of the balloon when it passes over the school is 1,175 feet.
The correct answer is C. 1,175 feet.
Aaron works 3
1
2
hours every Saturday at a rate of $7.25 per hour. He is paid every four weeks. If his boss gives him a $1.00 raise, how much will Aaron be paid in his next paycheck?
A.
$95.70
B.
$101.50
C.
$108.90
D.
$115.50
To find Aaron's pay in his next paycheck, we need to calculate his current pay per hour and then multiply it by the number of hours he works.
Aaron currently earns $7.25 per hour.
With a $1.00 raise, his new pay rate is $7.25 + $1.00 = $8.25 per hour.
Aaron works 3.5 hours every Saturday.
His pay for one Saturday is $8.25 * 3.5 = $28.875.
Since Aaron is paid every four weeks, his paycheck will include 4 Saturdays.
Therefore, the total amount Aaron will be paid in his next paycheck is $28.875 * 4 = $115.50.
The correct answer is D. $115.50.
Jason is saving up for a skateboard and helmet. The skateboard is $45.50 with tax and the helmet is $18.25 with tax. He earned
1
3
of the money by mowing lawns and the rest by babysitting. How much did Jason earn babysitting?
A.
$19.13
B.
$21.25
C.
$30.33
D.
$42.50
To find out how much Jason earned babysitting, we need to subtract the amount he earned from mowing lawns from the total amount he saved.
The skateboard costs $45.50 and the helmet costs $18.25, so the total cost is $45.50 + $18.25 = $63.75.
Jason earned 1/3 of the total money by mowing lawns. So, 1/3 of $63.75 is (1/3) * $63.75 = $21.25.
Therefore, Jason earned $21.25 babysitting.
The correct answer is B. $21.25.

To determine which expression results in a negative number, we need to evaluate each expression and see if the result is negative.
A. 1/2(−2×25) = 1/2(-50) = -25. This is negative.
B. 1/3(−18)÷−3 = (-6) ÷ (-3) = 2. This is positive.
C. −1/4(−7−6) = -1/4(-13) = 13/4. This is positive.
D. −1/2 ÷ −2/3 = (-1/2) ÷ (-2/3) = 3/4. This is positive.
Therefore, only expression A results in a negative number.
The correct answer is A. 1/2(−2×25).
