Jack wants to buy a coat that costs $74.95. The sales tax rate in his city is 6,4%. What is the total cost for the coat? Round to the nearest cent

$79.7468

Step-by-step explanation:

6.4% of 74.95 is 4.7968, since 6.4 * 74.95 is 479.68, and if you divide that by 100, you will get 4.7968. 4.7968 + 74.95 = $79.7468

15 batches are the most you can make

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
