Gym a:
$65 + $20 per month
$65 + 20m m=month
gym b:
$25 + $35 per month with 20% discount
$25 + $28m
2x + y = 350
x + 2y = 475
3x + 3y = 825
x + y = 275
x = 275 - y
(plug back into first equation)
2(275 - y) + y = 350
550 - 2y + y = 350
550 - y = 350
-y =-200 or y = $200 (dog)
therefore, x = $75 (cats)
Check
2(75) + 200 = 350
75 + 400 = 475
HAPPINESS! :)
Answer:
Step-by-step explanation:
A recipe for 1 loaf of bread calls for 2 cups of flour, 12 tablespoons of water and 1 teaspoon of salt.
Therefore, if we add 2 loaves of bread then double of ingredients will be required for the recipe.
In the same way if 4 loaves of bread have been added, 4 times ingredients will be required.
If 3 cups of flour are added then 3 times of other ingredients will be required.
So the table will be,
Number of loaves Cups of flour Tablespoons of water Teaspoons of salt
1 2 12 1
2 4 24 2
4 8 48 4
3 6 36 3
Answer:
6 cookies
Step-by-step explanation:
first, find how much money they spent on cupcakes
6 × $2.25 = $13.5
then, take $13.5 and subtract that by $24
$24 - $13.5 = $10.5
so the person spent $10.5 on cookies. divide the amount per cookie by $10.5
$10.5 ÷ $1.75 = 6
so they bought 6 cookies
