Question

PLEASE HELP ASAP ILL GIVE YOU 30 POINTS Jamie is excited for spring break this year. Her family is planning a vacation! She fully intends to take 20 pictures each day. checking her phone before leaving she notices she has 75 pictures already on the phone.

Given that the vacation will last a full seven days and Jamie's phone can hold a total of 200 pictures. How many pictures will she need to delete an order to make enough room in her phone for vacation photos?

Answer 1

15 photos

Explanation:

one can start off by first seeing how many photos will be taken on the vacation. We can do that by multiplying the days with how many photos will be taken for each- so 20×7= 140. Then we can take the total amount of photos the phone cam hold-200 subtract what we already have 200-75= 125 thats how much space if left but we need more (140). So the. we can start making quick guesses by taking 5 from 75 and see what we get then taking another 5 and another if needed we get 60 that finally gives when subtracted from 200- 200-60=140 the amount of space we need. Then finally we can just do 75-60 to get the total amount of photos we must delete. 75-60= 15

Answer 2

The answer is 15
Since 20 times 7 is 140 and 140+75 is 215
Take 215-200 you get 15
