Step-by-step explanation:

I= (4 + x ) * 5 E= x

I: 52 more than Emma

(4+x) * 5 = x + 52

20 + 5x = x + 52

5x - x = 52 - 20

4x = 32

x = 8

so then

E= 8

I= 12 × 5 = 60

Mashutka [201]

Answer:

The total amount of money received at the lemonade stand was $49.50

Step-by-step explanation:

Let

x ---> the number of small drinks sold

y ---> the number of medium drinks sold

we know that

The stand sold 72 drinks

$x+y=72$ ----> equation A

The ratio of small drinks to medium drinks sold was 5:3

$\frac{x}{y}=\frac{5}{3}$

$x=\frac{5}{3}y$ ----> equation B

substitute equation B in equation A

$\frac{5}{3}y+y=72$

$\frac{8}{3}y=72\\\\y=72(3)/8\\\\y=27$

Find the value of x

$x=\frac{5}{3}(27)=45$

Find out the total amount of money received at the lemonade stand

$0.50(45)+1.00(27)=\$49.50$
