To solve this problem, we need to multiply the number of packages of hot dog buns Mr. Spencer bought for the picnic (30) times the number of hot dogs per package (8) to find the number of hot dogs total that were purchased.
8 * 30 = 240
Therefore, Mr. Spencer bought 240 hot dogs for the school picnic.
Hope this helps!
For the first blank, the answer should be the total weight of the solution which is derived from adding 5 grams and 20 grams. The answer would be,
T = 5 + 20 = 25 grams
For the second blank, the % solution is derived by dividing the amount of salt initially by the total amount of the resulting solution. This is as shown below.
C = ((20 x 0.5) / 25) x (100%)
Simplifying,
C = 40%
Answers:
a. 25 grams
b. 40%
I think the answer is 1.38 times 10^7.
