Because you are solving to find the total amount and you were given that the tax is 8% you’d do $999 times 0.08 and you’d get $79.92 and then you’d add $79.92 to $999 to find the total amount charge to his card and you’d get $1078.92

A student has test scores of 68%, 75%, and 79% in a government class. What must she score on the last exam to earn a B (80% or b

FinnZ [79.3K]

68% +75 % +79 % +x ÷4≥ 80%
.68 + .75 + .79+x ÷4* 4 ≥ . 80*4
.68 + .75 + .79+x ≥ 3.2
2.22 + x ≥ 3.2
2.22 -2.22+x ≥ 3.2 -2.22
x ≥ 0.98
She has to get at least 98% to get an B.

As treasurer of his school's FFA club, Kenny wants to buy gifts for all 18 members. He can buy t-shirts for $9 and sweatshirts f

DanielleElmas [232]

Kenny can buy 15 t shirts and 3 sweatshirts.

Step-by-step explanation:

Given,

Number of members = 18

Cost of each t shirt = $9

Cost of each sweatshirt = $15

Money = $180

Let,

x be the number of t shirts

y be the number of sweatshirts

According to given statement;

x+y=18 Eqn 1

9x+15y=180 Eqn 2

Multiplying Eqn 1 by 9

$9(x+y=18 )\\9x+9y= 162\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(9x+15y)-(9x+9y)=180-162\\9x+15y-9x-9y=18\\6y=18\\$

Dividing both sides by 6

$\frac{6y}{6}=\frac{18}{6}\\y=3$

Putting y=3 in Eqn 1

$x+3=18\\x=18-3\\x=15$

Kenny can buy 15 t shirts and 3 sweatshirts.
