The question is about the number we need to add both sides. It is 64
Answer:
She uses 243 beads for the 5th string.
Step-by-step explanation:
In this problem, we can see a pattern. If she triples the number of beads in each of the next strings, that means that we just take the last number and multiply by 3. If the first string uses 3, then:
The second uses 9, 3 * 3 = 9
The third uses 27, 9 * 3 = 27
The fourth uses 81, 27 * 3 = 81
And the 5th uses 243, 81 * 3 = 243.
Assuming that they each work 24hrs a day 7 days a week (I haven't got anything else to go on...sorry) to find the total for Joshua you must first multiply 13x24 = 312, for the toys sold per day, and then 312x7 = 2184, for the number of days per week. so j = 2184
then for Sarah's total we must first multiply 16x24 = 384 for the toys sold per day and then 384x7 = 2688 for the toys sold per week. and 2688+20 = 2708 for the extra 20 she sold. so s = 2708
REMEMBER, THIS IS ASSUMING THEY WORK 24/7 MEANING THEY WORK 168 HOURS PER WEEK.
IF YOU NEED A DIFFERENT ANSWER LET ME KNOW AND I'LL TRY TO FIX IT. IF YOU LET ME KNOW THE HOURS THEY WORKED I CAN DO TAT FOR YOU AS WELL.
