brice and thomas are reading the same book l. the graph shows the number of pages that brice read in a week

the equation y= 21x + 33 shows the number of pages that thomas read in a week with y
representing the number of pages and x representing the number of days.

which statements about the reading of the two boys are true?

select each correct answer

1) thomas is reading at a faster rate than brice

2) thomas reads 20 pages each day.

3) brice reads 33 pages each day.

4) brice started the week with more pages read than thomas.

marco saved more.   he saved $35 more.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
