We can infer that more cups of flour are needed as the cakes are increased, so we can apply a rule of three, simple with direct proportion to find the answer:
12 cakes ----> 22 cups flour
30 cakes ----> x
x = (30)(22)/12
x = 55
therefore 55 cups of flour are needed to bake 30 cakes
The true statements about Marcus graph are:
- The initial cost of phone service 1 is greater than the initial cost of phone service 2
- The unit rate of phone service 2 is greater than the unit rate of phone service 2
<h3>How to determine the true statement</h3>
From the complete question, we have the following parameters:
<u>Phone service 1</u>
- Initial cost: $40
- Rate: $8.50 per service
<u>Phone service 2</u>
- Initial cost: $30
- Rate: $10.50 per service
By comparing the above parameters:
- The initial cost of phone service 1 is greater than the initial cost of phone service 2
- The unit rate of phone service 2 is greater than the unit rate of phone service 2
The above statements represent the true statements about the Marcus' graph
