A grocery store offers a coupon for $2 off when a customer buys 6 or more bottles of water. The water costs $1.75 per bottle. Shauna uses the function t (b) = 1.75b – 2 to find the total t dollars it costs to buy b bottles of
water. When she uses the function to find how many bottles she can buy for $5, she finds b = 3.4, so she
concludes she could buy 3 bottles of water for $5 Explain what error
Shauna made.

step-by-step explanation:

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
