A chef uses 5 pounds of flour to bake 120 blueberry muffins.
Cloud [144]

Answer:

A

Step-by-step explanation:

You can solve this problem by setting up a ratio. 5 pounds of flour makes 120 muffins, so the ratio of pounds of flour to muffins is 5:120=1:24. This means that you can make 24 muffins with 1 pound of flour. Multiplying both of these by 2, you get 24*2=48 muffins with two pounds of flour, or answer choice A. Hope this helps!

Alex73 [517]

Answer:

286 students attended

148 non students attended

Step-by-step explanation:

Given

Tickets = 434

Students = \$4.00

Non-Students = \$6.00

Total = \$2032.00

Solving (a): Number of students

Represent students with S and non students with N

So:

S + N = 434 --- (1)

4S + 6N = 2032 --- (2)

Make N the subject of formula in (1)

N = 434 - S

Substitute 434 - S for N in (2)

4S +6(434 - S) = 2032

Open Bracket

4S + 2604 - 6S = 2032

Collect Like Terms

4S - 6S = 2032 - 2604

-2S = -572

Divide through by -2

S = 286

<em>Hence; 286 students attended</em>

Solving (b):

Recall that

N = 434 - S

N = 434 - 286

N = 148

<em>148 non students attended</em>
