Answer: b
Step-by-step explanation:
10 x 10= 100
15 x 10= 150
100+150= 250
One pie costs 0.10
you are buying 40 pies so...
40 x 0.10 = $4
one cup of coffee costs 0.50
you are buying 20 coffee so...
20 x 0.50 = $10
$4 + $10 = $14
It costs $14 to buy 40 pieces of pie and 20 cups of coffee
Change 1/4 to 2/8 and then add. the answer is 7 7/8.
