A store sold 14 more colored shirts than white shirts. The white shirts cost $9.95 and colors cost $10.50. If a total of $310.60

Andrej [43]

9514 1404 393

Answer:

8 white shirts
22 colored shirts

Step-by-step explanation:

Let c represent the number of colored shirts sold. Then c-14 is the number of white shirts sold. The total revenue is ...

10.50c +9.95(c -14) = 310.60

20.45c -139.30 = 310.60 . . . . . . simplify

20.45c = 449.90 . . . . . . . . . . add 139.30

c = 22 . . . . . . . . . . . . . . . . . divide by 20.45

c-14 = 8

22 colored shirts and 8 white shirts were sold.

Can someone help me please??<br>

oksian1 [2.3K]

Answer:

Step-by-step explanation:

Comparing like terms on both sides

$x^{6}$ → x²

Note that x² = $\sqrt[3]{x^{6} }$

$y^{12}$ → $y^{4}$

Note that $y^{4}$ = $\sqrt[3]{y^{12} }$

Also

54 → 3

Note that 54 = 3³ × 2

and $\sqrt[3]{54}$ = $\sqrt[3]{3^{3}(2) }$ = 3 $\sqrt[3]{2}$

Hence

$\sqrt[3]{54x^{6}y^{12} }$ = 3x² $y^{4}$ $\sqrt[3]{2}$

Hence n = 3 → B

For each function below, determine whether or not the function is injective and whether or not the function is surjective. Be su

olga55 [171]

Answer:

The function is neither injective nor surjective

Step-by-step explanation:

f: P({1,2,3}) -> N is given by f(A) = |A|

where P(S) denotes the power set of a set S and |A| the number of elements of A

$P(\left \{ 1,2,3 \right \})=\left \{ \varnothing ,\left \{ 1 \right \},\left \{ 2 \right \},\left \{ 3 \right \},\left \{ 1,2 \right \},\left \{ 1,3 \right \},\left \{ 2,3 \right \},\left \{ 1,2,3 \right \} \right \}$

$f(\varnothing )=0$

$f(\left \{ 1 \right \})=f(\left \{ 2 \right \})=f(\left \{ 3 \right \})=1$

$f(\left \{ 1,2 \right \})=f(\left \{ 1,3 \right \})=f(\left \{ 2,3 \right \})=2$

$f(\left \{ 1,2,3 \right \})=3$

The function is not injective, for

$P(\left \{ 1 \right \})=P(\left \{ 2 \right \})$

but

$\left \{ 1 \right \}\neq \left \{ 2 \right \}$

The function is not surjective either, because 5 is a natural number which is not the image of any element A under f, i.e., there is no element in A in P({1,2,3}) such that f(A)=5
