The Amount of water passing through a dam is f(t)=-1.5^2+78t+800 million liters. What is the rate of water after 10 days?

Sally gave 30 shells to Jason

Solution:

Given that, Sally found 58 seashells on the beach, she gave Jason some of her seashells

She has 28 left

To find: Number of sea shells she gave to Jason

From given,

Total number of shells she found = 58

Remaining shells = 28

Therefore,

Number of sea shells she gave to Jason = Total number of shells she found - Remaining shells

Number of sea shells she gave to Jason = 58 - 28 = 30

Thus Sally gave 30 shells to Jason
