Final answer:
To find the number of gummies John and Ashley have altogether, use the information given to determine their individual quantities and then add them together. Frank has 363 gummies, John has 213 gummies, and Ashley has 264 gummies. Therefore, John and Ashley have a total of 477 gummies.
Step-by-step explanation:
To find the number of gummies John and Ashley have altogether, we need to determine their individual quantities of gummies and then add them together. Let's solve the problem step-by-step:
Let's assume Frank has x gummies.
According to the given information, John has 150 gummies less than Frank, so John has (x - 150) gummies.
Frank has 99 gummies more than Ashley, so Ashley has (x - 99) gummies.
The total number of gummies is given as 840, so we can write the equation:
x + (x - 150) + (x - 99) = 840
Simplifying the equation, we get:
3x - 249 = 840
Adding 249 to both sides, we get:
3x = 1089
Dividing both sides by 3, we get:
x = 363
Therefore, Frank has 363 gummies, John has (363 - 150) = 213 gummies, and Ashley has (363 - 99) = 264 gummies.
The number of gummies John and Ashley have altogether is:
= 213 + 264
= 477 gummies.
