A recipe calls for 3/4 cup of butter. Angie wants to triple the recipe, but she has only 1 5/8.How much butter must she borrow from a neighbor?

Answers

Answer 1

Answer: Let's start out by tripling the original recipe to see how much butter Angie needs.

$(3)/(4) * 3 = total$
$(3* 3)/(4) = total$
$(9)/(4) = total$
$2 (1)/(4) = total$

So we need $2 (1)/(4)$ cups of butter, but Angie only has $1 (5)/(8)$ . Let's subtract what Angie has from the total to see how much more she needs.

$2 (1)/(4) - 1(5)/(8) = n$
$(9)/(4) - (13)/(8) = n$
we will need the least common denominator for both fractions
$(2)/(2) *((9)/(4)) - (13)/(8) = n$
$(18)/(8) - (13)/(8) = n$
$(5)/(8) = n$

So Angie need $(5)/(8)$ cups more of butter for the recipe.

Nelson Middle school raised 19,950 on ticket sales for its carnival fundraiser last year at $15 per ticket. If the school sells the same number of tickets this year but charges $20 per ticket,how much money will the school make

Answers

For last year the school raised $19 950 tickets sold at $15 per ticket:

Number of tickets sold = $19 950 / $15 = 1330 tickets were sold

So if each ticket is now sold for $20,

Total = 1330 * 20 = $26, 600 for this year.

So this year the school will raise $26 600, which is more than last year.

I hope this explains it.

19950/15 = 1330 tickets sold last year

1330 * 20 = 26,600 <== the school will make $ 26,600
