A meal plan lets students buy $20 meal cards. Each meal card lasts about 8 days. write and graph equation

Luda [366]

Step-by-step explanation:

Given that,

A meal plan lets students buy $20 meal cards.

Each meal card lasts about 8 days.

Let us assume that y denotes number of days for a 20 dollar meal card i.e. $20 every 8 days.

Let x = number of $ for another day.

So,

$y=\dfrac{8}{20}x+8$

$y=\dfrac{2}{5}x+8$

Hence, this is the required equation.

The cost of two tables and three chairs is $705. If the table costs $40 more than the chair,find the cost of the table and the c

Nadusha1986 [10]

Answer:

the cost of the table is $\$165$

the cost of the chair is $\$125$

Step-by-step explanation:

Let

x-----> the cost of the table

y----> the cost of the chair

we know that

$2x+3y=705$ -----> equation A

$x=y+40$ -----> equation B

substitute equation B in equation A

$2(y+40)+3y=705$

$2y+80+3y=705$

$5y=705-80$

$y=625/5$

$y=\$125$

Find the value of x

$x=y+40$ ----> $x=125+40=\$165$
