Step-by-step explanation:
Answer: the bus would be used 30 times for the monthly costs to be the same.
Step-by-step explanation:
Let x represent the number of times in a month for which the bus must be used so the total monthly cost is the same with the book as it is without it.
The bus fare without a coupon book is $1.50. This means that the total monthly cost of using the bus for x times without a coupon book is 1.5x
A coupon book cost $30.00 and with the coupon book, the fare is reduced $0.50. This means that the total monthly cost of using the bus for x times with a coupon book is
0.5x + 30
For the monthly costs to be the same,
1.5x = 0.5x + 30
1.5x - 0.5x = 30
x = 30
We need 75 quarts of 3% butterfat milk. How much of 2% and 5% do we need to mix? (t = 2% and f = 5%)
A) t + f = 75
B) .02 t + .05 f = (.03 * 75)
B) .02 t + .05 f = 2.25
Solving for t and f:
t = 50 quarts of 2 % and
f = 25 quarts of 5%
Double-Check
50 * .02 = 1 quart of buttermilk
25 * .05 = 1.25 quarts of buttermilk
2.25 quarts divided by 75 quarts = 3 % buttermilk
