Which answer describes the calculations that could be used to solve this problem?

mike bought 7 tickets for the baseball game. each ticket cost $8. he gave the cashier a $100 bill. how much change would mike get?

a.
add $8 + 7. then subtract the sum from $100.

b.
multiply $100 × 7. then add $8 to the product.

c.
divide $100 ÷ 7. then add 8 to the quotient.

d.
multiply 7 × $8. then subtract the product from $100

D. Since we know that 1 ticket = $8 we would multiply to figure out how much 7 tickets were. (7x$8). And to figure out his change you would subtract the ticket amount from $100 :) Hope this helps

What you do is add 8+8+8+8+8+8+8 so the simple form is 8x7, and then you subtract 100 and you should get your answer.

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
