Peter bought 6 mangos at $x each. He also bought a papaya for $5. If x =2, find the total cost of the fruits.

Total cost of all fruits = $17

Step-by-step explanation:

Given:

Number of mangoes Peter bought = 6

Cost of each mango = x

Cost of papaya = $5

Find:

Total cost of all fruits if x = 2

Computation:

If x = 2

So,

Cost of each mango = x

Cost of each mango = $2

Cost of 6 mangoes = 6 × Cost of each mango

Cost of 6 mangoes = 6 × 2

Cost of 6 mangoes = $12

Total cost of all fruits = Cost of 6 mangoes + Cost of papaya

Total cost of all fruits = 12 + 5

Total cost of all fruits = $17

Y= -1x-1

Step-by-step explanation:

The slope is going down in a 1 to 1 ratio, so the slope is -1. The line crosses the x axis at -1, so the y intercept is -1
