A man bought four cups of coffee and left a $7 tip. A woman bought eight cups of coffee and only left a $2 tip. If they paid the same amount, how much was each cup
of coffee
a $1.10
b. $2.25
c. $0.7
d. $1.25

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

many reason,

step-by-step explanation:

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
