William had $50 for breakfast money. then he spent $2 for breakfast each day for 5 days. which equation can be used to determine the number of dollars, d, william has left at the end of the 5 days? a. 50 / 2(5) = d b. 50 + 2(5)= d c. 50 (times)2(5)=d d. 50 - 2(5) = d

Hello!

The equation that can be used to determine the number of dollars William has left at the end of 5 days is D. 50 - 2(5) = d

Think about it. We will have to multiply the $2 he spent everyday by the 5 days, and then we'll have to SUBTRACT that to find how much money he has left at the end.

Have a great day!

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
