Mark often buys lunch at the deli next to his work. Lunch at the deli costs $7.50. Mark sets aside $150 for lunches at the deli at the beginning of the month. Which equation describes how much money, y, Mark has after eating lunch at the deli x times during the month?

y = 150 - 7.50x

Step-by-step explanation:

Given that:

Cost per lunch = 7.50

Amoint budgeted for lunch = $150

The equation which models the amount of money, y Mark has after eating x times at the Deli

Amount left = Amount budgeted for lunch - (cost per lunch * number of lunch eaten)

y = $150 - ($7.50 * x)

y = 150 - 7.50x

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
