Answer:
The best option is c
Step-by-step explanation:
The same textbooks contains a total of 848 pages . Which represent the total number of pages , y , of any number of the same textbooks , x.
The number of same text book = x
Each of this textbook contains a total of 848 pages .
The total number of pages can be computed as
y = 848x
for 4 same text book
y = 848 × 4 = 3392 pages
for 3 same text book
y = 848 × 3= 2544 pages
for 7 same text book
y = 848 × 7 = 5936 pages
for 8 same text book
y = 848 × 8 = 6784 pages
for 11 same text book
y = 848 × 11 = 9328 pages
A would be 1 as b would be -4
Answer:
X = 9 months
Step-by-step explanation:
To solve the number of months when the cost of each payment
are the same, you should equate the two cost. First establish the equations
Let A be the cost of first payment method
B is the cost of the second payment method
X is the number of months
A = 38x + 15
B = 31x + 78
38x + 15 = 31x + 78
7x = 63
X = 9 months
