Levart [38]

Answer:

you need 6 cups of raisins, 4 cups of granola and 8 cups of blueberries.

Step-by-step explanation:

Step 1: Find how much raisins are needed

For 4.5 cups of fruity granola, we need 1.5 cups of raisins

For 18 cups of fruity granola, we need y cups of raisins

4.5 : 1.5

18 : y

Cross multiply

4.5y = 1.5 x 18

y = 27/4.5

y = 6 cups of raisins

Step 2: Find how much granola is needed

For 4.5 cups of fruity granola, we need 1 cup of granola

For 18 cups of fruity granola, we need y cups of granola

4.5 : 1

18 : y

Cross multiply

4.5y = 18

y = 4 cups of granola

Step 3: Find how much blueberries are needed

For 4.5 cups of fruity granola, we need 2 cups of raisins

For 18 cups of fruity granola, we need y cups of blueberries

4.5 : 2

18 : y

Cross multiply

4.5y = 2 x 18

y = 36/4.5

y = 8 cups of blueberries

Therefore, in order to make 18 cups of fruity granola, you need 6 cups of raisins, 4 cups of granola and 8 cups of blueberries.

Henry sells rings for $8 dollars each his expenses are $1.50 per ring plus $91 for supplies how many rings does he need to sell

Ne4ueva [31]

Henry needs to sale 14 rings for his revenue to equal his expenses.

Step-by-step explanation:

Given,

Selling price of ring = $8

Expense on one ring = $1.50

Cost of supplies = $91

Let,

x represent the number of rings.

Expenses = 91+1.50x

Revenue = 8x

Equal expenses means;

Revenue = Expenses

$8x=91+1.50x\\8x-1.50x=91\\6.5x=91$

Dividing both sides by 6.5

$\frac{6.5x}{6.5}=\frac{91}{6.5}\\x=14$

Henry needs to sale 14 rings for his revenue to equal his expenses.
